I'm just getting started with Ruby and need one of my applications to 
parse an XML file provided by a client.  I've been looking at using 
REXML, but I have a feeling there might be a XML parser library included 
in the Ruby 1.8 distribution.  Am I mistaken or just blind?  I noticed 
it has a YAML parsing library, which is what makes me think there's 
probably an XML parsing one too.

Thanks in advance for any advice!
