Question

I am creating an xslt and xml file dynamically to show my questionnaire & save my question options (for dropdown). Now I want to use stream instead of writing on actual file. So this is how I am doing it:

XmlReader xslt_reader;
XmlReader xml_reader;

PageLoad(){
  Fn_CreateXSL();
  Fn_CreateXML();
  LoadQuestionnaire();
}

Fn_CreateXSL(){
   xslt_stream = new MemoryStream();

   XmlTextWriter objXSLTWriter = new XmlTextWriter(xslt_stream, Encoding.UTF8);

   objXSLTWriter.Formatting = Formatting.Indented;
   objXSLTWriter.WriteStartDocument();
    ..........
   objXSLTWriter.WriteEndDocument();
   xslt_stream.Seek(0, SeekOrigin.Begin);
   xslt_reader = XmlReader.Create(xslt_stream);
}

Fn_CreateXML(){
   xmlt_stream = new MemoryStream();

   XmlTextWriter objXMLTWriter = new XmlTextWriter(xmlt_stream, Encoding.UTF8);

   objXMLTWriter.Formatting = Formatting.Indented;
   objXMLTWriter.WriteStartDocument();
    ..........
   objXMLTWriter.WriteEndDocument();
   xmlt_stream.Seek(0, SeekOrigin.Begin);
   xmlt_reader = XmlReader.Create(xmlt_stream);
}

LoadQuestionnaire(){
  XslCompiledTransform var_xsl_trans = new XslCompiledTransform();

  // also tried var_xsl_trans.Load(xslt_reader, null, new XmlUrlResolver());
  var_xsl_trans.Load(xslt_reader); // XSLT Compile Error occurs

  StringWriter sw = new StringWriter();

  var_xsl_trans.Transform(xml_reader, null, sw);
}

But I am getting “XSLT Compile Error when I’m trying to load it. Any idea?

As @kevin mentioned in the comment, the following fixed my issue, but I am not quite sure why it worked though (have some idea, but not sure)

Add objXMLTWriter.Flush() before the xmlt_stream.Seek(0,
SeekOrigin.Begin);
