  Hey

  you can try somethine like this:

           XmlDocument xmlDoc = new XmlDocument();
          xmlDoc.LoadXml(file);
          XmlNodeList nodeList = xmlDoc.SelectNodes("root/node");

          foreach (XmlNode xmlNode in nodeList)
          {
            string strName = xmlNode.Attributes["val"].Value;
            int intStatsValue = Convert.ToInt32(xmlNode.InnerText);

             //now you can store and compare the values
          }
   

   

  Hope this helps.

  In XPath try this:

  /root/node[not(@val <= preceding-sibling::node/@val) and not(@val <=following-sibling::node/@val)]

  Have a look into this link. It uses a function math:max. It has a link for source for that function and explains how it can be implemented

  Hope this helps you
