Example:-
We can use getElementByTagName together with namespace prefix to access the element value:-
xmlDoc.getElementsByTagName("ns0:POID")[0].firstChild.nodeValue ;
Whole code to access the XML data with namespace prefix via getElementsByTagName:-
<html><head>
<script language="javascript">
function getXML()
{
var xmlstring = "<?xml version='1.0' ?><ns0:PO xmlns:ns0='http://www.abc.com/PO'><ns0:POID>PO123</ns0:POID><ns0:CustomerID>ABC007</ns0:CustomerID></ns0:PO>";
if (window.DOMParser)
{
parser=new DOMParser();
xmlDoc=parser.parseFromString(xmlstring,"text/xml");
}
else // Internet Explorer
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async="false";
xmlDoc.loadXML(xmlstring);
}
var x = xmlDoc.getElementsByTagName("ns0:POID")[0].firstChild.nodeValue ;
alert(x);
}
</script>
</head><body onload="javascript:getXML()">
</body></html><?xml version='1.0' ?>
<ns0:PO xmlns:ns0='http://www.abc.com/PO'>
<ns0:POID>PO123</ns0:POID>
<ns0:CustomerID>ABC007</ns0:CustomerID>
</ns0:PO>
