IXMLDOMDocumentType

Contains information associated with the document type declaration.

Example

The C/C++ example below displays the doctype name of the document. The example uses an XML resource file, books1.xml.

XML Resource file: books1.xml

Remarks

Each DOMDocument includes a doctype that identifies the document's IXMLDOMDocumentType. The IXMLDOMDocumentType provides access to the list of entities and notations defined for the document.

Requirements

Implementation:

Msxml3.dll, msxml2.lib (MSXML 3.0)

msxml6.dll, msxml6.lib (MSXML 6.0)

Header and IDL files: msxml2.h, msxml2.idl, msxml6.h, msxml6.idl

Versioning

Implemented in: MSXML 3.0, MSXML 6.0
