Abstract
In an XML handling system, point updates to an element of an XML document stored in the database is possible. Updates include addition or deletion of whole documents, addition of a child node to any element node (this includes attribute nodes), the addition of new siblings to any element node, the deletion of any element node, and the replacement of any node by a new node. The database system might include a set of functions that can be invoked to affect an update (i.e., an addition, deletion or modification). Such updates can be submitted as queries, such as instructions within an XQuery query.
