Example

The following script example creates an IXMLDOMNodeList object by using the document's getElementsByTagName method.

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0");
var objNodeList;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode <> 0) {
   var myErr = xmlDoc.parseError;
   alert("You have error " + myErr.reason);
} else {
   objNodeList = xmlDoc.getElementsByTagName("author");
   alert(objNodeList.length);
   for (var objNode in objNodeList)
      alert(objNode.xml);
}

Example

The following Microsoft® Visual Basic® example creates an IXMLDOMNodeList object by using the document's getElementsByTagName method, and examines the content of each node.

Dim xmlDoc As New Msxml2.DOMDocument50
Dim objNodeList As IXMLDOMNodeList
Dim objNode As IXMLDOMNode
xmlDoc.Load ("books.xml")
If (xmlDoc.parseError.errorCode <> 0) Then
   Dim myErr
   Set myErr = xmlDoc.parseError
   MsgBox("You have error " & myErr.reason)
Else
   Set objNodeList = xmlDoc.getElementsByTagName("author")
   MsgBox objNodeList.length
   For Each objNode In objNodeList
      MsgBox objNode.xml
   Next
End If

Example

The following C/C++ example gets all elements with node name AUTHOR and displays the number of nodes found with the following sample.

<?xml version='1.0'?>
