The XMLDOMNodeList Object

You use the XMLDOMNodeList to handle lists of nodes, and node lists are useful because a node can itself have many child nodes. Using a node list, you can handle all the children of a node at once.

For example, here I'm loading a document and getting a list of all <PERSON> elements as a node list, using the document object's getElementsByTagName method:

function readXMLDocument() 
{
    var xmldoc, nodeList
    xmldoc = new ActiveXObject("Microsoft.XMLDOM")
    xmldoc.load("ch07_01.xml")
    nodeList = xmlDoc.getElementsByTagName("PERSON")
    .
    .
    .

Here is the base set of properties for the XMLDOMNodeList object:

• length— Number of items in the collection. Read-only.
