How to parse CDATA using DOM parser?

Here is the xml:
<?xml version="1.0" encoding="UTF-8" ?>
<abc xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="H:\abc.xsd"><body><payload>
<![CDATA[<Envelope xmlns="http://www.department.com/abc">
<Body>
<Company>
<Employee name="">
<Employee employeeid="123" versionId="1">1440848757001</Employee >
<EventCd reasonCd="direct">VALID</EventCd>
</Employee >
</Company>
</Body>
</Envelope>]]></payload></body></abc>

You may simply parse it as a simple content of a child node (using the property: data)

in JavaScript (+-AJAX)

Code:

var content=xmldocument.documentElement.getElementsByTagName('payload')[0].firstChild.data;

To prevent a crossbrowser problem regarding the counting of the child nodes (IE vs other browsers) you may use a small function and check the nodeType:

Code:

var content=returnCDATA(xmldocument.documentElement.getElementsByTagName('payload')[0].firstChild);
function returnCDATA(elem){
while(elem.nodeType!=4){
elem=elem.firstChild;
}
return elem.data;
}
