Hi shayken,
Do like this, create a dom and load the secondary xml in that. From that you can get the data what ever you want.
see the below code.
IXMLDomDocument <docName> = thisXDocument.createDOM();
<docName>.Load(“xml file”);
by using <docName> you retrieve the node value what ever you want.
Hope this will help you.
