//XPathDocument src = new XPathDocument(oSrcAllXMLReader); XPathNavigator srcnav = oSrcXMLDoc.CreateNavigator(); //XPathDocument des = new XPathDocument(oDesXMLReader); XPathNavigator desnav = oDesXmlDoc.CreateNavigator(); MessageBox.Show(desnav.OuterXml); srcnav.MoveToRoot(); srcnav.MoveToFirstChild(); do { do { desnav.MoveToRoot(); desnav.MoveToFirstChild(); Boolean found = false; do { do { if (srcnav.Name == desnav.Name) { string tmpval = srcnav.Value.ToString(); if (tmpval != null && tmpval.Length > 0) { desnav.SetValue(tmpval); } found = true; } } while (desnav.MoveToChild(XPathNodeType.Element) && found == false); } while (desnav.MoveToNext(XPathNodeType.Element) && found == false); } while (srcnav.MoveToChild(XPathNodeType.Element)); } while (srcnav.MoveToNext(XPathNodeType.Element)); MessageBox.Show(desnav.OuterXml);
