[W3af-develop] XSS context detection performance improvements

[Andres R. <and...@gm...>]

List, Taras,

    After finding a bug where the context detection for XSS was
performing very poorly [0] (more than 3 minutes to run get_context on
an HTML) I decided to work a little bit on it and improve it.

    The performance improvement was amazing ;) The changes are well
documented here [1][2]

    When I started running the test suite for context detection took
2.5 seconds, now after the performance improvements it takes 0.098
seconds! Not bad, huh?

    @Taras: Since you wrote that code in the first place you might be
interested in taking a look at the improvements and correcting any
mistakes I might have made. Thanks!
