Are you trying to replace all "config" elements in all documents in a
collection? If replacement nodes are all the same, there is no need to
have a loop, and the query may look similar to this:
<xupdate:modifications version='1.0'
xmlns:xupdate='http://www.xmldb.org/xupdate'>
<xupdate:rename select='/site/config'>config1</xupdate:rename>
<xupdate:insert-before select='/site/config1'>
<xupdate:element name="config">
<xupdate:element name="icon">images/myicon.jpg</xupdate:element>
<xupdate:element name="title">My great new site</xupdate:element>
</xupdate:element>
</xupdate:insert-before>
<xupdate:remove select='/site/config1'>
</xupdate:remove>
</xupdate:modifications>
Even if the replacement nodes are different, I would recommend to move
the query for deleting nodes out of the loop - each query results in
iterating over all documents in a collection, that would affect
execution time of the code.
