Microsoft DOM Objects Reference

getNamedItem()

Syntax

Set objXMLDOMNode = objXMLDOMNamedNodeMap.getNamedItem(strAttributeName)

Remark

The XMLDOMNamedNodeMap object is used to find and manipulate attributes for a Node, although the XMLDOMElement interface gives you many methods as well to do this.

This method takes the name of an attribute to find the Node associated with that attribute. However, to be able to do this, we first need to get a hold of the XMLDOMNamedNodeMap object, which is the attributes property of a Node. If there are attributes in the current Node, then we can query the XMLDOMNamedNodeMap collection.

Example

In the following example, we want to store the value of the elements ID attribute in the tag of a TreeView. We have already loaded a DOMDocument from our people2.xml. We have passed a person element in the following example.

Dim objNode As IXMLDOMNode

Dim objAttributes As IXMLDOMNamedNodeMap

Dim objAttributeNode As IXMLDOMNode

Set objAttributes = objNode.Attributes

If objAttributes.length > 0 Then

Set objAttributeNode = objAttributes.getNamedItem("PERSONID")

tvwElement.Tag = objAttribute-Node.nodeValue

End If

¬ Get the XMLDOMNamedNodeMap from the Nodes attribute property.

¬ Check that there are available attributes.

¬ Our id reference is "PERSONID"; therefore, tell the NameNodeListMap to get this Node by using the getNamedItem method.
