libxml2 has XPath support. Bindings against libxml2 are provided by
many languages, e.g. you could install the libxml2-python package from
CentOS 4. Besides that, it is relatively easy to write a C program that
uses libxml2 to evaluate XPath expressions (which is handy for shell
scripting). A quick and dirty example can be found at:
http://danieldk.org/code/snippets/xpgrep-0.0.1.tar.gz
(I wrote/use it as a minimal grep workalike that accepts XPath
expressions).
BTW. If you have files that are not well-formed (like many XHTML)
files, or if the information to extract is trivial, it is often easier
to grep or write a simple line-processing Perl script.
