C#

1. If you don't already have one, add a reference to System.Xml.Linq;
2. Add using System.Linq; and using System.Xml.Linq; at the top of your code file;
3. Use:
   C#

   XElement el = XElement.Parse(sReturnString);
   string sCredits = (string)el.Elements("data").Elements("credits").FirstOrDefault();
   return "Balance: " + sCredits;

string s = "<api_result><data><credits>33</credits></data><call_result><result>True</result><error /></call_result></api_result>" ;

System.Xml.XmlDocument doc = new System.Xml.XmlDocument() ;
doc.LoadXml ( s ) ;

System.Xml.XmlNode nod = doc.DocumentElement.SelectSingleNode ( "data/credits" ) ;

string v = nod.InnerText ;
