Both XPath and CSS are standards, understood by browsers. You don't need
jQuery to use CSS selectors.

We have a simple parser which works on some malformed HTML when the built
in parser fails.

As to why XPath instead of CSS? I believe the nth-of-type selectors and
such are only since CSS3. The types of queries we use XPath for have been
supported much longer.

These days you might be able to accomplish the same with CSS but this is
case is exactly what XPath was designed for.
