Namespace BasicDom

Contains classes which provide the standard implementation for Document Object Model (DOM) and Extended Document Model (XDM).

Classes of this namespace implement, with some restrictions, DOM Level 1 as described in Document Object Model (DOM) Level 1 Specification.

The Extended Document Model provides the proprietary representation of XML documents specially designed for use with XSLT and XPath processing algorithms. XDM, as well its relation to DOM, is discussed in details in the description of Dom namespace.

The following DOM features are not supported by the current implementation of BasicDom :

• default attribute values specified in DTD are not assigned automatically as required by the DOM specification
• the value of the doctype attribute of Document interface is always null, therefore objects implementing DocumentType , Notation and Entity interfaces are not accessible
• operation getElementsByTagName of Document interface is not implemented
• operation isSpecified of Attr interface always returns true
• operation getElementsByTagName of Element interface is not implemented
• operation normalize of Element object is not implemented
• the special semantics for child lists of EntityReference nodes and the read-only property for descendants of EntityReference nodes are not implemented.

This means, in particular, that, once BasicDom implementation of DOM is considered:

• Dom::IDocument::GetDoctype always returns NULL
• Dom::IDocument::GetElementsByTagName always returns NULL
• Dom::IElement::IsSpecified always returns true
• Dom::IElement::GetElementsByTagName always returns NULL
