There is pretty good documentation at
http://www.germane-software.com/software/rexml/

I need some some details regarding how its implemented in REXML and
HPRICOT.

Why do you care how it's implemented? For REXML you can look it up in
the sources.

Kind regards

What's the actual problem you need to solve? Besides the problem "my program
does not have enough XPath in it yet"?

This post shows some great ways to learn XPath notation:

http://www.oreillynet.com/onlamp/blog/2007/08/xpath_checker_and_assert_xpath.html

Briefly, you install either XPath Checker or XPather into your Firefox. Then
load your XML (or XHTML) into the browser, and hit "View XPath". The checker
will reflect the elements that an XPath expression returns. Edit the expression
to see what happens, and learn how XPath predicates and axes work.
