Parameters

name

A string specifying the name of the attribute.

Return Value

xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode <> 0) {
   var myErr = xmlDoc.parseError;
   alert("You have error " + myErr.reason);
} else {
   nodeBook = xmlDoc.selectSingleNode("//book");
   nodeId = nodeBook.attributes.getNamedItem("id");
   alert(nodeId.value);
}

Visual Basic Syntax

Set objXMLDOMNode = oXMLDOMNamedNodeMap.getNamedItem(name)

Parameters

name

A string specifying the name of the attribute.

Return Value

An object. Returns an IXMLDOMNode object for the specified attribute. Returns Nothing if the attribute node is not in this collection.

Example

Dim xmlDoc As New Msxml2.DOMDocument50
Dim nodeBook As IXMLDOMElement
Dim nodeId As IXMLDOMAttribute
xmlDoc.async = False
xmlDoc.Load "books.xml"
If (xmlDoc.parseError.errorCode <> 0) Then
   Dim myErr
   Set myErr = xmlDoc.parseError
   MsgBox("You have error " & myErr.reason)
Else
   Set nodeBook = xmlDoc.selectSingleNode("//book")
   If TypeName(nodeBook.Attributes.getNamedItem("id")) <> "Nothing" Then
      Set nodeId = nodeBook.Attributes.getNamedItem("id")
      MsgBox nodeId.Value
   Else
