From 586849318286965d6ede2932ccd31176b4f7fe81 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Reuse xmlHaltParser() where it makes sense
To: libvir-list@redhat.com

Unify the various place where either xmlStopParser was called
(which resets the error as a side effect) and places where we
used ctxt->instate = XML_PARSER_EOF to stop further processing
