Question

My XML

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE task  "sdlGeneralTask.dtd"[]>
<task id="1234" xml:lang="en">
  <title id="12345">For Validation Test</title>
  <taskbody cid="345">
    <steps id="1263">
      <step cid="324">
        <cmd>Test operation for validation.</cmd>
      </step>
    </steps>
  </taskbody>
</task>

MY XSLT

<?xml version="1.0" encoding="iso-8859-1"?>   
<html xsl:version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/xhtml">    
    <body style="font-family:Arial;font-size:12pt;background-color:#FFFFFF">    
        <xsl:for-each select="task">    
            <div style="background-color:teal;color:white;padding:4px">    
                <span style="font-weight:bold">    
                    <xsl:value-of select="node"/>    
                </span>
            </div>    
             
        </xsl:for-each>    
    </body>    
</html>

public static string TransformXMLToHTML(string inputXml, string xsltString)
        {
            XslCompiledTransform transform = new XslCompiledTransform();
            using (XmlReader reader = XmlReader.Create(new StringReader(xsltString)))
            {
                transform.Load(reader); //getting error at this point
            }
            StringWriter results = new StringWriter();
            using (XmlReader reader = XmlReader.Create(new StringReader(inputXml)))
            {
                transform.Transform(reader, null, results);
            }
            return results.ToString();
        }
