Converting a System.Xml.XmlDocument to XML type in Dynamics ax

When interacting with .Net assemblies mostly  Xml is used to send/receive outputs from the external system. Here is a code snippet that tells how to convert a System.Xml.XmlDocument to a Xml string in Ax which you can use for further processing by classes like XmlDocument…

//CLR Objects
System.Xml.XmlDocument document;
System.Xml.XmlTextWriter textWriter;
System.IO.StringWriter   stringwriter;

//X++ Objects
Xml                      Xml
;

//call to the .Net assembly that returns a XML
document    = processINput(...argument..)

stringWriter = new System.IO.StringWriter();
textWriter   = new System.Xml.XmlTextWriter(stringwriter);

document.writeTO(textWriter);

//Converted to Ax Xml format here
xml        = stringWriter.ToString();
