Answer 1

Curl, and once ure in, use QueryPath php library. (querypath.org) You can access dom elements just like in JQuery, via CSS selectors, there's method chaining...

Way better than just using php's native xml functions.

It also works as drupal extension, but I suppose you could implement it in any php project.
