XslCompiledTransform.Load raises Object reference not set to an instance of an object

While loading xslt in XslCompiledTransform, I am getting Object reference not set to an instance of an object.

I fetched following xslt from database: -

<xsl:stylesheet version=\"1.0\" xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\">
<xsl:template match=\"/\">
   <html>
      <body>
        <h2>My CD Collection</h2>
        <table border=\"1\">
            <tr bgcolor=\"#9acd32\">
               <th style=\"text-align:left\">Title</th>
               <th style=\"text-align:left\">Artist</th>
             </tr>
            <xsl:for-each select=\"catalog/cd\">
             <tr>
               <td>
                    <xsl:value-of select=\"title\"/>
               </td>
               <td>
                    <xsl:value-of select=\"artist\"/>
               </td>
             </tr>
           </xsl:for-each>
        </table>
      </body>
   </html>
</xsl:template>
</xsl:stylesheet>

and following xml from database :-

<?xml version="1.0" encoding="UTF-8"?>
<catalog>
   <cd>
      <title>Empire Burlesque</title>
      <artist>Bob Dylan</artist>
      <country>USA</country>
      <company>Columbia</company>
      <price>10.90</price>
      <year>1985</year>
   </cd>
</catalog>

When using following code to transform xslt : -

public static string XsltTransform(string xmlContent, string xsltContent)
{
    string result = string.Empty;
    XmlTextReader xtr = new XmlTextReader(new StringReader(xsltContent));
    xsltCompiled.Load(xtr);

    using (StringReader srXml = new StringReader(xmlContent))
    {
        using (XmlReader xrXml = XmlReader.Create(srXml))
        {
            using (StringWriter sw = new StringWriter())
            {

                xsltCompiled.Transform(xrXml, null, sw);

                result = sw.ToString();
            }
        }
    }
    return result;
}

But it throws error "Object reference not set to an instance of an object" at line :-

xsltCompiled.Load(xtr);

Any suggestions?

Updates: Just to add more I am getting this after create XmlTextReader : -

enter image description here

static void Main(string[] args) { string xmlContent = File.ReadAllText("D:/test/data.xml"); string xsltContent = File.ReadAllText("D:/test/style.xslt"); string result = XsltTransform(xmlContent, xsltContent.Replace("\\\"", "\"")); } static readonly XslCompiledTransform XsltCompiled = new XslCompiledTransform(); public static string XsltTransform(string xmlContent, string xsltContent) { string result = string.Empty; XmlTextReader xtr = new XmlTextReader(new StringReader(xsltContent)); XsltCompiled.Load(xtr); using (StringReader srXml = new StringReader(xmlContent)) { using (XmlReader xrXml = XmlReader.Create(srXml)) { using (StringWriter sw = new StringWriter()) { XsltCompiled.Transform(xrXml, null, sw); result = sw.ToString(); } } } return result; }
