[jabber.el] GTalk Connection trouble/Patch

[Ashutosh G. <ash...@gm...>]

Hi,

I have been using emacs-jabber-7.1 for connecting to gtalk. I found some
times it is failing to parse the xml packate received from gtalk. If anyone
remember i contacted few months back for buggy behavior of jabber.el while
connecting with gtalk.Now, i have found the problem and its probable
solution.

Let me first explain you with the problem,

While connecting to gtalk server i was seeing following  error  message:

Debugger entered--Lisp error: (error "XML: End tag for iq not found before
end of region")
  signal(error ("XML: End tag for iq not found before end of region"))
  error("XML: End tag for %s not found before end of region" "iq")

I looked into and found that problem is combination of the packet filter of
jabber-core.el, gtalk and xml.el in emacs library.
some times gtalk sends xml packets which has a space at the end i.e.
"<i>m</i> ".  jabber-xml-skip-tag-forward (function in jabber-xml.el) ask
xml-parse-region to parse only till last ">" and call (xml-parse-region 1
9). xml-parse-region should successfully parse it but it fails. ( xml.el in
emacs must have a bug.)

[If you don't understand my English then ask me i will send test code to
demonstrate the problem.]

Solution:
But if you call  (xml-parse-region 1 10), then it works fine.
So the solution is, in function jabber-xml-skip-tag-farward (in
jabber-xml.el) add following line:

                                       until (looking-at (regexp-quote
(concat "</" node-name ">")))
                                       do (jabber-xml-skip-tag-forward))
line no 119-->              (goto-char (match-end 0))
 +++Add this line-->   (skip-chars-forward " ")
                                      t)

Please note main developers of emacs-jabber.
