What I'm doing is parsing Wikipedia Categories. Using Physics as the example Input, the script would request this page.
EG: the first one on the page is Category:Applied and interdisciplinary physics, so the script will then request this page.

Then as above, all the page elements with ns attribute of zero are pages and saved for later, and the elements with ns attribute of 14 are added to the list of sub-categories to walk.

Once all the the subcategories are traversed, then operations are performed on the list of unique articles.

Basically what is happening is given the input, the script should walk all the branches of the tree 'below' it.
