I know what you're saying Buck, but I'm sure going into the DB2 XML
functions would be as 'interesting' as regex on XML.

Using DB2 XML functionality is fundamentally different to regex in that
you know the structure, so you specify the XPath to be queried. DB2
does the dirty work and gives you the contents of the tag. You do your
text compare / replace and then tell DB2 to write the thing out and DB2
takes on the responsibility of keeping the XML document sane.

Using a regex means that you need to do all the dirty work yourself, and
there is almost certainly going to be some goofy edge case where having
a script write the XML document is going to unbalance a tag or do some
other structural damage to the document. Oh, and reading that regex a
month from now is going to give me headaches. Er, I mean you. I wasn't
talking about me trying to do something like this, no, never :-)
