IXMLDOMAttribute

Example

The following script example creates an IXMLDOMAttribute object from the first attribute of the root and displays the object's value and xml properties.

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0");
var root;
var objDOMatt;
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode <> 0) {
   var myErr = xmlDoc.parseError;
   alert("You have error " + myErr.reason);
} else {
   root = xmlDoc.documentElement;
   objDOMatt = root.firstChild.attributes.item(0);
   alert(objDOMatt.value);
   alert(objDOMatt.xml);
}

Example

The following Microsoft® Visual Basic® example creates an IXMLDOMAttribute object from the first attribute of the root and displays the object's value and xml properties.

Dim xmlDoc As New Msxml2.DOMDocument50
Dim root As IXMLDOMElement
Dim objDOMatt 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 root = xmlDoc.documentElement
   Set objDOMatt = root.firstChild.Attributes.Item(0)
   MsgBox (objDOMatt.Value)
   MsgBox (objDOMatt.xml)
End If

IXMLDOMAttribute inherits IXMLDOMNode but are not actually child nodes of the element and are not considered part of the document tree. Attributes are considered members of their associated elements rather than independent and separate. Thus IXMLDOMAttribute parentNode, previousSibling, and nextSibling members have the value Null.
