XML DOM Navigating Node

Navigating Node is the process by which we can access the node in the node three by the relationship between node. In XML DOM Node relationship have following properties.

  • parentsNodes
  • childNodes
  • firstChild
  • LasdChild
  • priviousSibling
  • nextSibling

Following example navigate the parents node of  "myfile.xmlk".

<html>

<head>

<script type="text/javascript" src="myfile.js">

</script>

</head>

<body>

 

<script type="text/javascript">

    Doce = loadXMLDoc("personDetail.xml");

 

    str = Doce.getElementsByTagName("person")[0];

    document.write(str.parentNode.nodeName);

</script>

</body>

</html>

 

Following example will display first child node of "person" element.

 

<html>

<head>

<script type="text/javascript" src="myfile.js">

</script>

<script type="text/javascript">

   

    function getfirstnode(p) {

     x = p.firstChild;

        while (x.nodeType != 1) {

         x = x.nextSibling;

        }

        return x;

    }

</script>

</head>

 

<body>

<script type="text/javascript">

 doce = loadXMLDoc("Detail.xml");

 

 str = getfirstnode(doce.getElementsByTagName("person")[0]);

    document.write(str.nodeName);

</script>

</body>

</html>
