public class CmsXmlPage
extends A_CmsXmlDocument

Implementation of a page object used to access and manage xml data.

This implementation consists of several named elements optionally available for various languages. The data of each element is accessible via its name and language. The content of each element is stored as CDATA, links within the content are processed and are separately accessible as entries of a CmsLinkTable.
