Abstract
Various techniques are described hereafter for improving the efficiency of updating XML documents in a content repository, such as a database system. Specifically, techniques are described for updating an XML document by dynamically merging a stream of XML data from the document with update information. Techniques are also described for efficient validation of XML documents. Because of the manner of the updates, specifically because the XML data being updated is in the form of a stream, the database system validates only those portions of the stream of XML data that have been updated. In the alternative, the database system validates that portion of the XML data that is associated with the parent node of the portion of XML data that has been updated.
