1. What is RapidXml?

RapidXml is an attempt to create the fastest XML DOM parser possible, while retaining useability, portability and reasonable W3C compatibility. It is an in-situ parser written in C++, with parsing speed approaching that of strlen() function executed on the same data.

- Entire parser is contained in a single header file, so no building or linking is neccesary. To use it you just need to copy rapidxml.hpp file to a convenient place (such as your project directory), and include it where needed. You may also want to use printing functions contained in header rapidxml_print.hpp.

1.1 Dependencies And Compatibility

RapidXml has no dependencies other than a very small subset of standard C++ library (<cassert>, <cstdlib>, <new> and <exception>, unless exceptions are disabled). It should compile on any reasonably conformant compiler, and was tested on Visual C++ 2003, Visual C++ 2005, Visual C++ 2008, gcc 3, gcc 4, and Comeau 4.3.3. Care was taken that no warnings are produced on these compilers, even with highest warning levels enabled.

1.2 Character Types And Encodings

RapidXml is character type agnostic, and can work both with narrow and wide characters. Current version does not fully support UTF-16 or UTF-32, so use of wide characters is somewhat incapacitated. However, it should succesfully parse wchar_t strings containing UTF-16 or UTF-32 if endianness of the data matches that of the machine. UTF-8 is fully supported, including all numeric character references, which are expanded into appropriate UTF-8 byte sequences (unless you enable parse_no_utf8 flag).

- Note that RapidXml performs no decoding - strings returned by name() and value() functions will contain text encoded using the same encoding as source file. Rapidxml understands and expands the following character references: &apos; &amp; &quot; &lt; &gt; &#...; Other character references are not expanded.

1.3 Error Handling

By default, RapidXml uses C++ exceptions to report errors. If this behaviour is undesirable, RAPIDXML_NO_EXCEPTIONS can be defined to suppress exception code. See parse_error class and parse_error_handler() function for more information.

1.4 Memory Allocation

RapidXml uses a special memory pool object to allocate nodes and attributes, because direct allocation using new operator would be far too slow. Underlying memory allocations performed by the pool can be customized by use of memory_pool::set_allocator() function. See class memory_pool for more information.

1.5 W3C Compliance

RapidXml is not a W3C compliant parser, primarily because it ignores DOCTYPE declarations. There is a number of other, minor incompatibilities as well. Still, it can successfully parse and produce complete trees of all valid XML files in W3C conformance suite (over 1000 files specially designed to find flaws in XML processors). In destructive mode it performs whitespace normalization and character entity substitution for a small set of built-in entities.

1.6 API Design

RapidXml API is minimalistic, to reduce code size as much as possible, and facilitate use in embedded environments. Additional convenience functions are provided in separate headers: rapidxml_utils.hpp and rapidxml_print.hpp. Contents of these headers is not an essential part of the library, and is currently not documented (otherwise than with comments in code).

1.7 Reliability

RapidXml is very robust and comes with a large harness of unit tests. Special care has been taken to ensure stability of the parser no matter what source text is thrown at it. One of the unit tests produces 100,000 randomly corrupted variants of XML document, which (when uncorrupted) contains all constructs recognized by RapidXml. RapidXml passes this test when it correctly recognizes that errors have been introduced, and does not crash or loop indefinitely.

- Another unit test puts RapidXml head-to-head with another, well estabilished XML parser, and verifies that their outputs match across a wide variety of small and large documents.

- Yet another test feeds RapidXml with over 1000 test files from W3C compliance suite, and verifies that correct results are obtained. There are also additional tests that verify each API function separately, and test that various parsing modes work as expected.

1.8 Acknowledgements

I would like to thank Arseny Kapoulkine for his work on pugixml, which was an inspiration for this project. Additional thanks go to Kristen Wegner for creating pugxml, from which pugixml was derived. Janusz Wohlfeil kindly ran RapidXml speed tests on hardware that I did not have access to, allowing me to expand performance comparison table.

2. Two Minute Tutorial

2.1 Parsing

The following code causes RapidXml to parse a zero-terminated string named text: 
using namespace rapidxml;
-xml_document<> doc;    // character type defaults to char
-doc.parse<0>(text);    // 0 means default parse flags
-
doc object is now a root of DOM tree containing representation of the parsed XML. Because all RapidXml interface is contained inside namespace rapidxml, users must either bring contents of this namespace into scope, or fully qualify all the names. Class xml_document represents a root of the DOM hierarchy. By means of public inheritance, it is also an xml_node and a memory_pool. Template parameter of xml_document::parse() function is used to specify parsing flags, with which you can fine-tune behaviour of the parser. Note that flags must be a compile-time constant.

2.2 Accessing The DOM Tree

To access the DOM tree, use methods of xml_node and xml_attribute classes: 
cout << "Name of my first node is: " << doc.first_node()->name() << "\n";
-xml_node<> *node = doc.first_node("foobar");
-cout << "Node foobar has value " << node->value() << "\n";
-for (xml_attribute<> *attr = node->first_attribute();
-     attr; attr = attr->next_attribute())
-{
-    cout << "Node foobar has attribute " << attr->name() << " ";
-    cout << "with value " << attr->value() << "\n";
-}
-

2.3 Modifying The DOM Tree

DOM tree produced by the parser is fully modifiable. Nodes and attributes can be added/removed, and their contents changed. The below example creates a HTML document, whose sole contents is a link to google.com website: 
xml_document<> doc;
-xml_node<> *node = doc.allocate_node(node_element, "a", "Google");
-doc.append_node(node);
-xml_attribute<> *attr = doc.allocate_attribute("href", "google.com");
-node->append_attribute(attr);
-
One quirk is that nodes and attributes do not own the text of their names and values. This is because normally they only store pointers to the source text. So, when assigning a new name or value to the node, care must be taken to ensure proper lifetime of the string. The easiest way to achieve it is to allocate the string from the xml_document memory pool. In the above example this is not necessary, because we are only assigning character constants. But the code below uses memory_pool::allocate_string() function to allocate node name (which will have the same lifetime as the document), and assigns it to a new node: 
xml_document<> doc;
-char *node_name = doc.allocate_string(name);        // Allocate string and copy name into it
-xml_node<> *node = doc.allocate_node(node_element, node_name);  // Set node name to node_name
-
Check Reference section for description of the entire interface.

2.4 Printing XML

You can print xml_document and xml_node objects into an XML string. Use print() function or operator <<, which are defined in rapidxml_print.hpp header. 
using namespace rapidxml;
-xml_document<> doc;    // character type defaults to char
-// ... some code to fill the document
-
-// Print to stream using operator <<
-std::cout << doc;   
-
-// Print to stream using print function, specifying printing flags
-print(std::cout, doc, 0);   // 0 means default printing flags
-
-// Print to string using output iterator
-std::string s;
-print(std::back_inserter(s), doc, 0);
-
-// Print to memory buffer using output iterator
-char buffer[4096];                      // You are responsible for making the buffer large enough!
-char *end = print(buffer, doc, 0);      // end contains pointer to character after last printed character
-*end = 0;                               // Add string terminator after XML
-

3. Differences From Regular XML Parsers

RapidXml is an in-situ parser, which allows it to achieve very high parsing speed. In-situ means that parser does not make copies of strings. Instead, it places pointers to the source text in the DOM hierarchy.

3.1 Lifetime Of Source Text

In-situ parsing requires that source text lives at least as long as the document object. If source text is destroyed, names and values of nodes in DOM tree will become destroyed as well. Additionally, whitespace processing, character entity translation, and zero-termination of strings require that source text be modified during parsing (but see non-destructive mode). This makes the text useless for further processing once it was parsed by RapidXml.

- In many cases however, these are not serious issues.

3.2 Ownership Of Strings

Nodes and attributes produced by RapidXml do not own their name and value strings. They merely hold the pointers to them. This means you have to be careful when setting these values manually, by using xml_base::name(const Ch *) or xml_base::value(const Ch *) functions. Care must be taken to ensure that lifetime of the string passed is at least as long as lifetime of the node/attribute. The easiest way to achieve it is to allocate the string from memory_pool owned by the document. Use memory_pool::allocate_string() function for this purpose.

3.3 Destructive Vs Non-Destructive Mode

By default, the parser modifies source text during the parsing process. This is required to achieve character entity translation, whitespace normalization, and zero-termination of strings.

- In some cases this behaviour may be undesirable, for example if source text resides in read only memory, or is mapped to memory directly from file. By using appropriate parser flags (parse_non_destructive), source text modifications can be disabled. However, because RapidXml does in-situ parsing, it obviously has the following side-effects:

4. Performance

RapidXml achieves its speed through use of several techniques:
  • In-situ parsing. When building DOM tree, RapidXml does not make copies of string data, such as node names and values. Instead, it stores pointers to interior of the source text.
  • Use of template metaprogramming techniques. This allows it to move much of the work to compile time. Through magic of the templates, C++ compiler generates a separate copy of parsing code for any combination of parser flags you use. In each copy, all possible decisions are made at compile time and all unused code is omitted.
  • Extensive use of lookup tables for parsing.
  • Hand-tuned C++ with profiling done on several most popular CPUs.
This results in a very small and fast code: a parser which is custom tailored to exact needs with each invocation.

4.1 Comparison With Other Parsers

The table below compares speed of RapidXml to some other parsers, and to strlen() function executed on the same data. On a modern CPU (as of 2007), you can expect parsing throughput to be close to 1 GB/s. As a rule of thumb, parsing speed is about 50-100x faster than Xerces DOM, 30-60x faster than TinyXml, 3-12x faster than pugxml, and about 5% - 30% faster than pugixml, the fastest XML parser I know of.
  • The test file is a real-world, 50kB large, moderately dense XML file.
  • All timing is done by using RDTSC instruction present in Pentium-compatible CPUs.
  • No profile-guided optimizations are used.
  • All parsers are running in their fastest modes.
  • The results are given in CPU cycles per character, so frequency of CPUs is irrelevant.
  • The results are minimum values from a large number of runs, to minimize effects of operating system activity, task switching, interrupt handling etc.
  • A single parse of the test file takes about 1/10th of a millisecond, so with large number of runs there is a good chance of hitting at least one no-interrupt streak, and obtaining undisturbed results.

class - template - rapidxml::memory_pool

- - Defined in rapidxml.hpp
- Base class for - xml_document

Description

This class is used by the parser to create new nodes and attributes, without overheads of dynamic memory allocation. In most cases, you will not need to use this class directly. However, if you need to create nodes manually or modify names/values of nodes, you are encouraged to use memory_pool of relevant xml_document to allocate the memory. Not only is this faster than allocating them by using new operator, but also their lifetime will be tied to the lifetime of document, possibly simplyfing memory management.

- Call allocate_node() or allocate_attribute() functions to obtain new nodes or attributes from the pool. You can also call allocate_string() function to allocate strings. Such strings can then be used as names or values of nodes without worrying about their lifetime. Note that there is no free() function -- all allocations are freed at once when clear() function is called, or when the pool is destroyed.

- It is also possible to create a standalone memory_pool, and use it to allocate nodes, whose lifetime will not be tied to any document.

- Pool maintains RAPIDXML_STATIC_POOL_SIZE bytes of statically allocated memory. Until static memory is exhausted, no dynamic memory allocations are done. When static memory is exhausted, pool allocates additional blocks of memory of size RAPIDXML_DYNAMIC_POOL_SIZE each, by using global new[] and delete[] operators. This behaviour can be changed by setting custom allocation routines. Use set_allocator() function to set them.

- Allocations for nodes, attributes and strings are aligned at RAPIDXML_ALIGNMENT bytes. This value defaults to the size of pointer on target architecture.

- To obtain absolutely top performance from the parser, it is important that all nodes are allocated from a single, contiguous block of memory. Otherwise, cache misses when jumping between two (or more) disjoint blocks of memory can slow down parsing quite considerably. If required, you can tweak RAPIDXML_STATIC_POOL_SIZE, RAPIDXML_DYNAMIC_POOL_SIZE and RAPIDXML_ALIGNMENT to obtain best wasted memory to performance compromise. To do it, define their values before rapidxml.hpp file is included.

Parameters

Ch
Character type of created nodes.

Synopsis

Ch* allocate_string(const Ch *source=0, std::size_t size=0); -

Description

Allocates a char array of given size from the pool, and optionally copies a given string to it. If the allocation request cannot be accomodated, this function will throw std::bad_alloc. If exceptions are disabled by defining RAPIDXML_NO_EXCEPTIONS, this function will call rapidxml::parse_error_handler() function.

Parameters

source
String to initialize the allocated memory with, or 0 to not initialize it.
size
Number of characters to allocate, or zero to calculate it automatically from source string length; if size is 0, source string must be specified and null terminated.

function memory_pool::clone_node

Synopsis

xml_node<Ch>* clone_node(const xml_node< Ch > *source, xml_node< Ch > *result=0); -

Description

Clones an xml_node and its hierarchy of child nodes and attributes. Nodes and attributes are allocated from this memory pool. Names and values are not cloned, they are shared between the clone and the source. Result node can be optionally specified as a second parameter, in which case its contents will be replaced with cloned source node. This is useful when you want to clone entire document.

Parameters

source
Node to clone.
result
Node to put results in, or 0 to automatically allocate result node

Returns

Pointer to cloned node. This pointer will never be NULL.

function memory_pool::clear

Synopsis

void clear(); -

Clears the pool. This causes memory occupied by nodes allocated by the pool to be freed. Any nodes or strings allocated from the pool will no longer be valid.

function memory_pool::set_allocator

Synopsis

void set_allocator(alloc_func *af, free_func *ff); -

Description

Sets or resets the user-defined memory allocation functions for the pool. This can only be called when no memory is allocated from the pool yet, otherwise results are undefined. Allocation function must not return invalid pointer on failure. It should either throw, stop the program, or use longjmp() function to pass control to other place of program. If it returns invalid pointer, results are undefined.

- User defined allocation functions must have the following forms:

-void *allocate(std::size_t size);
-void free(void *pointer);

Parameters

af
Allocation function, or 0 to restore default function
ff
Free function, or 0 to restore default function

class rapidxml::parse_error

- - Defined in rapidxml.hpp

Description

Parse error exception. This exception is thrown by the parser when an error occurs. Use what() function to get human-readable error message. Use where() function to get a pointer to position within source text where error was detected.

- If throwing exceptions by the parser is undesirable, it can be disabled by defining RAPIDXML_NO_EXCEPTIONS macro before rapidxml.hpp is included. This will cause the parser to call rapidxml::parse_error_handler() function instead of throwing an exception. This function must be defined by the user.

- This class derives from std::exception class.

- constructor - parse_error::parse_error

Synopsis

parse_error(const char *what, void *where); -

Description

Constructs parse error.

Description

Gets human readable description of error.

Returns

Pointer to null terminated description of the error.

function parse_error::where

Synopsis

Ch* where() const; -

Description

Gets pointer to character data where error happened. Ch should be the same as char type of xml_document that produced the error.

Returns

Pointer to location within the parsed string where error occured.

class - template - rapidxml::xml_attribute

- - Defined in rapidxml.hpp
- Inherits from - xml_base

Description

Class representing attribute node of XML document. Each attribute has name and value strings, which are available through name() and value() functions (inherited from xml_base). Note that after parse, both name and value of attribute will point to interior of source text used for parsing. Thus, this text must persist in memory for the lifetime of attribute.

Parameters

Ch
Character type to use.

- constructor - xml_attribute::xml_attribute

Synopsis

Parameters

Ch
Character type to use

- constructor - xml_base::xml_base

Synopsis

xml_base(); -

function xml_base::name

Synopsis

Ch* name() const; -

Description

Gets name of the node. Interpretation of name depends on type of node. Note that name will not be zero-terminated if rapidxml::parse_no_string_terminators option was selected during parse.

- Use name_size() function to determine length of the name.

Returns

Name of node, or empty string if node has no name.

function xml_base::name_size

Description

Gets size of node name, not including terminator character. This function works correctly irrespective of whether name is or is not zero terminated.

Returns

Size of node name, in characters.

function xml_base::value

Synopsis

Ch* value() const; -

Description

Gets value of node. Interpretation of value depends on type of node. Note that value will not be zero-terminated if rapidxml::parse_no_string_terminators option was selected during parse.

- Use value_size() function to determine length of the value.

Returns

Value of node, or empty string if node has no value.

function xml_base::value_size

Synopsis

std::size_t value_size() const; -

Description

Gets size of node value, not including terminator character. This function works correctly irrespective of whether value is or is not zero terminated.

Returns

function xml_base::name

Synopsis

void name(const Ch *name, std::size_t size); -

Description

- Note that node does not own its name or value, it only stores a pointer to it. It will not delete or otherwise free the pointer on destruction. It is reponsibility of the user to properly manage lifetime of the string. The easiest way to achieve it is to use memory_pool of the document to allocate the string - on destruction of the document the string will be automatically freed.

- Size of name must be specified separately, because name does not have to be zero terminated. Use name(const Ch *) function to have the length automatically calculated (string must be zero terminated).

name
Name of node to set. Does not have to be zero terminated.
size
Size of name, in characters. This does not include zero terminator, if one is present.

function xml_base::name

Synopsis

void name(const Ch *name); -

Description

Sets name of node to a zero-terminated string. See also Ownership Of Strings and xml_node::name(const Ch *, std::size_t).

Parameters

name
Name of node to set. Must be zero terminated.

function xml_base::value

Synopsis

void value(const Ch *value, std::size_t size); -

Description

Sets value of node to a non zero-terminated string. See Ownership Of Strings .

- Note that node does not own its name or value, it only stores a pointer to it. It will not delete or otherwise free the pointer on destruction. It is reponsibility of the user to properly manage lifetime of the string. The easiest way to achieve it is to use memory_pool of the document to allocate the string - on destruction of the document the string will be automatically freed.

- Size of value must be specified separately, because it does not have to be zero terminated. Use value(const Ch *) function to have the length automatically calculated (string must be zero terminated).

- If an element has a child node of type node_data, it will take precedence over element value when printing. If you want to manipulate data of elements using values, use parser flag rapidxml::parse_no_data_nodes to prevent creation of data nodes by the parser.

Parameters

- Inherits from - xml_node memory_pool

Description

This class represents root of the DOM hierarchy. It is also an xml_node and a memory_pool through public inheritance. Use parse() function to build a DOM tree from a zero-terminated XML text string. parse() function allocates memory for nodes and attributes by using functions of xml_document, which are inherited from memory_pool. To access root node of the document, use the document itself, as if it was an xml_node.

Synopsis

xml_document(); -

Description

Constructs empty XML document.

function xml_document::parse

Synopsis

void parse(Ch *text); -

Description

Parses zero-terminated XML string according to given flags. Passed string will be modified by the parser, unless rapidxml::parse_non_destructive flag is used. The string must persist for the lifetime of the document. In case of error, rapidxml::parse_error exception will be thrown.

- If you want to parse contents of a file, you must first load the file into the memory, and pass pointer to its beginning. Make sure that data is zero-terminated.

- Document can be parsed into multiple times. Each new call to parse removes previous nodes and attributes (if any), but does not clear memory pool.

Parameters

text
XML data to parse; pointer is non-const to denote fact that this data may be modified by the parser.

function xml_document::clear

Synopsis

void clear(); -

Description

- constant - parse_no_data_nodes

Synopsis

const int parse_no_data_nodes - = 0x1; -

Description

Parse flag instructing the parser to not create data nodes. Text of first data node will still be placed in value of parent element, unless rapidxml::parse_no_element_values flag is also specified. Can be combined with other flags by use of | operator.

- See xml_document::parse() function.

- constant - parse_no_element_values

Synopsis

const int parse_no_element_values - = 0x2; -

- See xml_document::parse() function.

- constant - parse_doctype_node

Synopsis

const int parse_doctype_node - = 0x80; -

Description

Parse flag instructing the parser to create DOCTYPE node. By default, doctype node is not created. Although W3C specification allows at most one DOCTYPE node, RapidXml will silently accept documents with more than one. Can be combined with other flags by use of | operator.

- See xml_document::parse() function.

- constant - parse_pi_nodes

Synopsis

const int parse_pi_nodes - = 0x100; -

- constant - parse_normalize_whitespace

Synopsis

const int parse_normalize_whitespace - = 0x800; -

Description

Parse flag instructing the parser to condense all whitespace runs of data nodes to a single space character. Trimming of leading and trailing whitespace of data is controlled by rapidxml::parse_trim_whitespace flag. By default, whitespace is not normalized. If this flag is specified, source text will be modified. Can be combined with other flags by use of | operator.

- See xml_document::parse() function.

- constant - parse_default

Synopsis

Description

Parse flags which represent default behaviour of the parser. This is always equal to 0, so that all other flags can be simply ored together. Normally there is no need to inconveniently disable flags by anding with their negated (~) values. This also means that meaning of each flag is a negation of the default setting. For example, if flag name is rapidxml::parse_no_utf8, it means that utf-8 is enabled by default, and using the flag will disable it.

This class is used by the parser to create new nodes and attributes, without overheads of dynamic memory allocation. - //! In most cases, you will not need to use this class directly. - //! However, if you need to create nodes manually or modify names/values of nodes, - //! you are encouraged to use memory_pool of relevant xml_document to allocate the memory. - //! Not only is this faster than allocating them by using new operator, - //! but also their lifetime will be tied to the lifetime of document, - //! possibly simplyfing memory management. - //!

- //! Call allocate_node() or allocate_attribute() functions to obtain new nodes or attributes from the pool. - //! You can also call allocate_string() function to allocate strings. - //! Such strings can then be used as names or values of nodes without worrying about their lifetime. - //! Note that there is no free() function -- all allocations are freed at once when clear() function is called, - //! or when the pool is destroyed. - //!

- //! It is also possible to create a standalone memory_pool, and use it - //! to allocate nodes, whose lifetime will not be tied to any document. - //!

- //! Pool maintains CEREAL_RAPIDXML_STATIC_POOL_SIZE bytes of statically allocated memory. - //! Until static memory is exhausted, no dynamic memory allocations are done. - //! When static memory is exhausted, pool allocates additional blocks of memory of size CEREAL_RAPIDXML_DYNAMIC_POOL_SIZE each, - //! by using global new[] and delete[] operators. - //! This behaviour can be changed by setting custom allocation routines. - //! Use set_allocator() function to set them. - //!

- //! Allocations for nodes, attributes and strings are aligned at CEREAL_RAPIDXML_ALIGNMENT bytes. - //! This value defaults to the size of pointer on target architecture. - //!

- //! To obtain absolutely top performance from the parser, - //! it is important that all nodes are allocated from a single, contiguous block of memory. - //!
