[jdev] parsing xml (xmpp) with ruby

[jlist]

I also find XMPP particularly difficult to parse.

In the case of a TLS connection, there's also the switch
from plain text to TLS...

I'm also coming to think that the best (or easiest) way
could be to use a SAX parser to parse out the stanzas, then
use a DOM parser for easy access to the attributes. However,
this may not handle the TLS's case though. I haven't looked
into the details but I suspect I need to handcraft the SAX
parser for the <stream> tags just to handle this scenario.
