[xml] Patch for xmlReplaceNode in tree.c

[Jurij Rosenthal <rosentha dvz-102 fh-muenster de>]

Hi all,

I see a problem with
http://cvs.gnome.org/lxr/source/gnome-xml/tree.c#2595
(yes, exactly that line).

The problem is that this does not set the doc pointer
for all child/property nodes of the node that replaces
the old node.

This might be also a problem since xmlSetTreeDoc() does
"deep" setting of the doc pointer only if the tree root node
has a doc pointer different from the new doc pointer.
See:
http://cvs.gnome.org/lxr/source/gnome-xml/tree.c#1804

I had crashes that indicate wrong doc pointers in nodes
after using xmlReplaceNode().

Patch attached.

Thank you,
Jurij Rosenthal
