  <p>Hello Dears.. I have an xml file. It contains different nodes with same node name. In the example under physicalResource node, I want to extract prName and all characteristic's name and value. But I cant parse them seperately.
  I'm using </p>
  
  <pre><code>nodeListPrs = root.SelectNodes("/physicalResource/physicalResourceCharacteristic/characteristic", nsmgr); 
  </code></pre>
  
  <p>It extracts all charactics value for both nodes. How can i extract these parameters from single physicalResource node?</p>
