XML File Upload and then Edit the Required Fields

Hi Friends,

My Requirement is to Upload the XML, and based on the selection screen values to change the values in the XML file and then download the changed XML file. I am able to Upload the XML and Download the same XML file using the interface IF_IXML_NODE, but i am not able edit the field values. As there are many child nodes i am facing problems. Can some you give any suggestions on this.

Thanks in Advance.
