Heres a quick example:

   string langid = "1";
   string catid  = "125";
   string result = "";

   string xpath = string.Format("//Language[@id='{0}']/subCat[@id='{1}']", langid, catid);

   XmlDocument xml = new XmlDocument();
   xml.Load("your xml document");
   XmlNode node = xml.SelectSingleNode(xpath);

   if ( node != null )
      result = string.Format("{0} > {1}", node.ParentNode.FirstChild.Attributes["name"].Value , node.Attributes["name"].Value);
      result = "No match found: " + xpath;

Hope this helps.
