  Hello, I am a newbie in Xpath. I have an XML document containing routing table shown below. I have been strugling for days on how to write xpath query to extract <agenttype> and <pref> nodes which destination address <startbrigade> is 7 AND <start_node> is 252  :'( .
  

  
  this is how i select out <pref> <agent type> and <start_node> in <brigade 7>
  

  
  System.Xml.XmlNodeList RouteList = xmldoc.SelectNodes("//startbrigade[. = '7']/ancestor::node()/pref | //startbrigade[. = '7']/ancestor::node()/agenttype|//startbrigade[. = '7']/parent::node()/start_node")
  

  
  but i want to further select out < pref >and <agenttype> which has <startnode> 252 only...
  

  
  Could anyone help please ?
