Erm...
CF on Linux -> use James Clarks Expat Parser for XML.
There isn't currently a simple CF interface for this though (one day...)
There is a simple Perl interface, and since you're on Linux, pass the
processing to something that can handle it. My best guess would be Perl.
The reason is that there are numerous XML modules for Perl, and they are
excellently supported by a mailing list.
Otherwise, if you are not getting complex data back (ie no CDATA sections)
then for the regex (bear in mind you can't really check whether it's an XML
packet beforehand so it's really only a hack) you need to take everything in
the <> and find everything up to the </> with the same name.
1) Create a structure to hold the XML (can store the whole thing as a
structure)
2) Then, find the first tag name (ie find a < and then the next bit of text
up to a ">" or a " ") and then find the attributes (everything up to the
next ">"...
3) Find the end tag for it (</__name__>)
4) everything in between is the data (which can contain XML)
5) pass the rest of the packet through the "parser"
Anyway, that's the way I'd do it. Maybe I'll try and do this!

PS: CDATA sections look like this:
