For XML handling I would use the XElement class (http://msdn.microsoft.com/en-us/library/system.xml.linq.xelement%28v=vs.110%29.aspx). You can find an example of its use at http://www.mssqltips.com/sqlservertip/1524/reading-xml-documents-using-linq-to-xml/. For querying your received XML, use Load or Parse methods to read it into a XElement, and use the Descendents, Element, Elements, Attribute, or Attributes methods and the Value property to read the data. To construct your response use the XElement constructor to create the elements and the Add method to add child elements to the hierarchy.
