I know they exist, and I'll try to list them here to get to the bottom of it.

When trying any science daily article we get:

Invalid argument supplied for foreach()

/home/travis/build/Nixes/PageScraper/lib.php:141
/home/travis/build/Nixes/PageScraper/lib.php:171
/home/travis/build/Nixes/PageScraper/lib.php:299
/home/travis/build/Nixes/PageScraper/tests/tests.php:36

This shouldn't happen, as we do hasChildren checks before this function (checkNode) is even run. Strange.
