Parsing and navigating XML tree in Windows Phone 7 (WP7)
Every time you need to go into a nested node use the ReadSubtree method and pass an XML string again to create a new XML reader to start from the top and skip to the next node of interest.

Use this function to process each specific node.

public void XmlToNxListingDetails(string xml) {
            NxDetailResultCollection col = new NxDetailResultCollection();
            XmlReaderSettings settings = new XmlReaderSettings();
            settings.IgnoreWhitespace = true;

            #region Get Found
            using (XmlReader xReader = XmlReader.Create(new StringReader(xml), settings)) {
                while (xReader.ReadToFollowing("found")) {
                    XMLHelper xHelp = new XMLHelper();
                    XmlNodeValue xnv = xHelp.GetNodeValue(xReader);
                    col.Found = xnv.NodeValue.ToInt();

            using (XmlReader xReader = XmlReader.Create(new StringReader(xml), settings)) {
                while (xReader.ReadToFollowing("nxlistingdata")) {
                    NxDetailResult cData = new NxDetailResult();

                    MapNxListingData(xReader.ReadSubtree(), cData);



private void MapNxListingData(XmlReader xmlReader, NxDetailResult cData) {


            XMLHelper xHelp = new XMLHelper();
            NxListingData item = new NxListingData();
            item.ListingAddress = new Address();
            item.CommunityAddress = new Address();

            do {
                XmlNodeValue xnv = xHelp.GetNodeValue(xmlReader);

                switch (xnv.NodeName) {                                      
                    case "communityupdatedate": item.CommunityUpdateDate = xnv.NodeValue.ToDate(); break;
                    case "communityattributes": MapCommunityAttribute(xnv.NodeValue, item); break;
                    case "communitymedia": MapCommunityMedia(xnv.NodeValue, item); break;
                    case "agent": MapAgent(xnv.NodeValue, item); break;
                    case "office": MapOffice(xnv.NodeValue, item); break;
                    case "datasource": MapDataSource(xnv.NodeValue, item); break;
                    case "advertiser": MapAdvertiser(xnv.NodeValue, item); break;
                    case "agentadvertiser": MapAgentAdvertiser(xnv.NodeValue, item); break;
                    case "officeadvertiser": MapOfficeAdvertiser(xnv.NodeValue, item); break;
            } while (!xmlReader.EOF);



 public XmlNodeValue GetNodeValue(XmlReader inner) {
            XmlNodeValue nv = new XmlNodeValue();

            if (inner.NodeType == XmlNodeType.Element) {
                nv.NodeName = inner.LocalName;// inner.Name;
                nv.NodeValue = inner.ReadInnerXml();
            } else if (inner.NodeType == XmlNodeType.EndElement) {
                nv.NodeName = inner.LocalName;// inner.Name;
                nv.NodeValue = inner.ReadInnerXml();
            } else if (inner.NodeType == XmlNodeType.Text) {
                nv.NodeName = inner.LocalName;// inner.Name;
                nv.NodeValue = inner.Value;
                if (string.IsNullOrEmpty(nv.NodeName)) {
                    nv.NodeName = inner.LocalName;// inner.Name;

            return nv;
