Nodes Accessing in XML

Nodes Accessing is the process by which we can access  to Nodes in XML document.  With DOM we can access in every Nodes in XML document. There are three way by which we can access the Nodes.

(1) getElementsByTagName() Method

When we use getElementByTagName() Method then its return all element with tag name.



In following example its return all "name" element under "sub" element.


In following example its return all "name" element under XML document.



(2) Using loop through a node list


We use loop through a node list by the using the length properties. Length properties defined the size of length.




xDoc = loadXMLDoc("Doce.xml");


    dd = xDoc.getElementsByTagName("name");

    for (i = 0; i < dd.length; i++) {


        document.write("<br />");



(3) Using Navigating Node Relationship


In following example we are using Navigating Node Relationship.


xDoc = loadXMLDoc("doc.xml");


    dd = xDoc.getElementsByTagName("name")[0].childNodes;

    mm = xDoc.getElementsByTagName("name")[0].firstChild;

    for (i = 0; i < dd.length; i++) {

        if (mm.nodeType == 3) {

            document.write(mm.nodeName + "<br />");


        mm = mm.nextSibling;
