if file isn't big (smaller few mb), can load xmldocument:

xmldocument doc = new xmldocument(); doc.load(@"c:\yourfile.xml");

and can parse <header> element using xpath expression:

xmlnode headernode = doc.selectsinglenode("/erecon/header"); if(headernode != null) {     string headernodexml = headernode.outerxml; }
