Validating XML Against XSD

Hello,

I have a XML document which complies to a XSD.I load the XML document and Parse the same using IXML Parser.The document thus loaded do have a schema binding indicated.But I find that parser does not validate the XML instance against the XSD.Please let me know how I can achieve this.In one of the previous posts I found that there is a class called CL_XML_SCHEMA which can be used to load a XSD.But how do I use this class when the XML instance itself comes along with the XSD reference?

Please help me out preferably with a working sample.

Regards

Sundar
