Enhance Extractor Node to Support Multiple Extraction Modes

[MertenD]

Description

Enhance the functionality of the Extractor Node to support multiple extraction modes. The node should be able to find either the first occurrence, all occurrences, or the nth occurrence of a specified pattern. Depending on the extraction mode, the node should output the results as a plain string/HTML or as an array of strings/HTML.

Tasks

• Implement a system for configuring the extraction mode within the Extractor Node.
• Design and implement updates to the user interface of the Extractor Node to support the new extraction modes.
• Develop backend functionality to perform the different types of extraction based on the configured mode.
• Ensure that the output of the Extractor Node is correctly formatted based on the extraction mode (plain string/HTML or array of strings/HTML).
• Ensure that the enhanced Extractor Node works seamlessly with the existing web crawler editor and execution engine.
• Test the enhanced Extractor Node thoroughly to ensure reliability and usability.
