Simon Greener, wrote an article on how to load GPX xml files into Oracle XMLDB. That
got me thinking that I haven't really explored all the XML features that PostgreSQL has to offer
and to some extent I've been reticent about XML processed in any database for that matter.
In this article we shall attempt to perform the same feats that Simon did, but with PostgreSQL instead of
Oracle XMLDB. Note while we are demonstrating this with a GPX file, the same XPath approach can be used to process any XML file.
