How to get the output of an XslCompiledTransform into an XmlReader?
- by Graham Clark
I have an XslCompiledTransform object, and I want the output in an XmlReader object, as I need to pass it through a second stylesheet. I'm getting a bit confused - I can successfully transform some XML and read it using either a StreamReader or an XmlDocument, but when I try an XmlReader, I get nothing.
In the example below, stylesheet is my XslCompiledTransform object. The first two Console.WriteLine calls output the correct transformed XML, but the third call gives no XML. I'm guessing it might be that the XmlTextReader is expecting text, so maybe I need to wrap this in a StreamReader..? What am I doing wrong?
MemoryStream transformed = new MemoryStream();
stylesheet.Transform(input, args, transformed);
transformed.Position = 0;
StreamReader s = new StreamReader(transformed);
Console.WriteLine("s = " + s.ReadToEnd()); // writes XML
transformed.Position = 0;
XmlDocument doc = new XmlDocument();
doc.Load(transformed);
Console.WriteLine("doc = " + doc.OuterXml); // writes XML
transformed.Position = 0;
XmlReader reader = new XmlTextReader(transformed);
Console.WriteLine("reader = " + reader.ReadOuterXml()); // no XML written
