Some ideas about the script

[Dither]

:contains pseudo-class is very incompatible with browsers (also deprecated in CSS3) so I've removed it from the script but some more xpathes can be safely converted. See my port for example.

Hi @Dither, I agree about :contains and would love to see your improvements.
Would you mind forking the repo, updating and sending me a pull request? That would definitely make it easier to see the changes you've made and incorporate them while keeping your ownership in them.

I am not proficient in python as in javascript so if you can't apply ideas from my javascript port (see the link in the first message) then I can't do much. >_>

The main ideas that applicable here are:

• splitting XPath for parts divided by |
• tag/following-sibling in the main navigation block -> +
• tag[1] - >:first-of-type
• tag[last()] -> :last-of-type

PS: I don't mind if you not mention my contribution because I believe that "copyrighting" small chunks of code is out of place practice.

oops, sorry. Didn't notice you actually made a full javascript port. Good job!
I'll check it out and see the important changes I can pull to the python version.
