Thanks for the quick reply.

I'm not familiar with configure scripts and I'm building on win32. Any
pointers? I think gmarkup was added in glib 1.3.2 (see
http://mail.gnome.org/archives/gtk-devel-list/2000-November/msg00147.html).
Perhaps we can just check for >= the current version?

XML that isn't supported will fail to parse but won't crash. I think the
gmarkup parse is broad enough to be useful. It works perfectly for my needs
(SOAP, UPnP, etc.).

I wrote it as a heuristic dissector within the "http" subdissector list. The
dissector checks for "<xml" at the start of the body and returns FALSE if it
doesn't match. Is there a better approach?
