I think the difference between both classes is clear, one is for XPath expressions and the other for XPointer ones, so I presume that you mean the examples are too similar and don't help to easily distinguish between both.

I can change it, but IMO the problem here is that XPointer extends the syntax and semantics of XPath and adds new locations (and syntax) for fragment identifiers, so we could consider XPointer a superset of XPath and use XPointerPointer also for XPath expressions.

Taking into consideration the previous statement, we may also consider merging both classes into a XPathXPointerPointer or something like that.

Exactly the same way.
