The `:contains()` selector is completely broken

Today I tried to use an old script that used to work. Unfortunately, it breaks at any usage of the `:contains()` selector. A minified example:

import pyquery query = pyquery.PyQuery('<html><p>foo</p></html>') query('p:contains("foo")')

--------------------------------------------------------------------------- XPathEvalError Traceback (most recent call last) <ipython-input-5-322269d1cc1f> in <module>() ----> 1 query('p:contains("foo")')

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
