Re: [Tclxml-users] why won't TclXML parse this?

Todd,

I have tried to write this three time and lost it when almost finished,
when Netscrape crashed. urk. So my tries at reply have been getting
briefer ..

No, its not really. Its not good having to admit that a basic compliance
feature is missing . But we seem to be short handed at the moment.

Thanks for the feedback Todd. Jabber is cool, and for some of our
favourite reasons (OS, XML, TCL). I hope we'll be able to get this fixed
for you as soon as we can.
Its interesting how Tcl does seem to have found a real niche in the
IRC/Chat/Instant Messaging world.
