Most efficient way to look for value in xml file?

Question

I have an XML file that I need to get some value from.

There are several ways to do it:

• XmlReader
• XmlDocument
• XDocument
• XmlTextReader

• XmlSerializer

  1. Can someone please explain when to use each of them?
  2. If I need just get one value from my XML file - which one should I use to do it the most efficient way ?

try this

string path = Server.MapPath("[pathofXMLFile]"); 
System.Xml.XmlDocument xml = new System.Xml.XmlDocument();
xml.Load(path);
System.Xml.XmlNodeList t = xml.GetElementsByTagName("[tagname]"); 
string ht = t[0].InnerXml;
