If the file is XHTML, it's XML, and you should use $parser->parse_file,
since parse_html_file is only intended for HTML, not XHTML.

You said, the file parsed ok, you only had problems accessing nodes in the 
parsed document. If you're using XPath (via findnodes, find, or findvalue), 
you're probably making the very common but wrong assumption that expressions 
like /html/body match the body element in the XHTML namespace.
See e.g. this thread for more info and several examples on how to treat 
documents with a default namespace:
