XML DOM Interfaces

---

This part of the XML DOM reference describes the programming interface syntax for C, C++, and Visual Basic developers. The following tables list the XML Document Object Model (DOM) programming interfaces by category.

XML DOM Interfaces

The following interfaces represent implementations of the XML DOM core interfaces, as well as Microsoft extensions to support namespaces, data types, XML schemas, XSL operations, asynchronous loading, and saving documents.

IXMLDOMDocument	Represents the top node of the XML DOM tree.
IXMLDOMNode	Represents a single node in the document tree; the base interface for accessing data in the XML object model. Valid node types are defined in the DOMNodeType enumeration. This interface includes support for data types, namespaces, DTDs, and XML schemas.
IXMLDOMNodeList	Supports iteration and indexed access operations on the live collection of IXMLDOMNode objects.
IXMLDOMNamedNodeMap	Provides iteration and access by name to the collection of attributes. This interface includes support for namespaces.
IXMLDOMParseError	Returns detailed information about the last error, including the line number, character position, and a text description.
IXMLHttpRequest	Provides a scriptable interface for sending and receiving XML via HTTP, including the ability to communicate with servers that support DAV.
IXTLRuntime	Implements methods that can be called from XSL style sheets.

DOM Object Interfaces

The following interfaces represent implementations of the XML DOM object interfaces.

IXMLDOMAttribute	Represents an attribute object.
IXMLDOMCDATASection	Quotes or escapes blocks of text so that text is not interpreted as markup.
IXMLDOMCharacterData	Provides text manipulation methods that are used by several objects.
IXMLDOMComment	Represents the content of an XML comment.
IXMLDOMDocumentFragment	Represents a lightweight object that is useful for tree insert operations.
IXMLDOMDocumentType	Contains information associated with the document type declaration.
IXMLDOMElement	Represents the element object.
IXMLDOMEntity	Represents a parsed or unparsed entity in the XML document.
IXMLDOMEntityReference	Represents an entity reference node.
IXMLDOMImplementation	Provides methods that are independent of any particular instance of the document object model.
IXMLDOMNotation	Contains a notation declared in the DTD or schema.
IXMLDOMProcessingInstruction	Represents a processing instruction, which XML defines to keep processor-specific information in the text of the document.
IXMLDOMText	Represents the text content of an element or attribute.

The DOMNodeType enumeration lists all valid node types.

Header Files

The interface header files can be obtained from the Web & Internet Samples Download Area. To download the header files:

1. You will first need to have Internet Explorer 5 installed.
2. From the Web & Internet Samples Download Area select Next  at the bottom right corner of the page.
3. A dialog appears asking if you would like to have an automatic search of your system to determine which components you need. Select No if you are only going to build XML applications.
4. Select Headers & Libraries for Internet Explorer 5 and Win32 Headers & Libraries for Windows 2000. Select Next .
5. Select where to download the files from.
6. Select Install Now, read the End User License Agreement, and select a location for the new headers and libraries; the default is C:\SBN. Start the installation.
7. Start Visual C++. Select Tools|Options|Directories. The choice lists should show Win32 for Platform and Include files for Show directories for .
8. Add C:\SBN\Include and C:\SBN\Include\NT5 to the top of the list of directories.
9. Change Show Directories for to Library files .
10. Add C:\SBN\Lib and C:\SBN\Lib\NT5 to the top of the list of directories.
