Abstract:
A system and method is provided for processing XQuery Updates on an Extensible Markup Language (XML) document. The XQuery Updates are processed in three phases. The first phase includes creating a pending update list (PUL) including all update operations to be performed on nodes in a fragment of the Extensible Markup Language (XML) document. The second phase includes sorting the PUL. The third phase includes applying the sorted PUL to each node in the XML fragment during a single traversal of the XML fragment.
