XDocument overview

XDocument is a software definitions for the XML document stored in external database. XDocument API provides direct access to stored information.

XDocument is essential component of the XStorage.

You can consider XDocument as a linked list of XNodes with attributes stored in external database. XDocument engine uses direct addressing inside XML tree and provides fast access to stored XML elements.

There is bidirectional conversion mechanism from DOM to XStorage, which provides compatibility with existing XML standards.

The major difference between XDocument and XML is that XDocument elements can be accessed directly and simultaneously. Another advantage of XDocument - it presents already parsed XML document and therefore reduces time necessary for parsing XML from text into DOM.
