Question

I have modified the title of the question after finding the answer 🙂 😛

I am loading an XML file and an XSL file by a C# program and triggering the XSL transformation .. here is the code for it:

static void Main(string[] args)
{

    // Create the XslCompiledTransform and load the stylesheet.
    XslCompiledTransform xslt = new XslCompiledTransform();
    xslt.Load("input.xsl");    //located in Debug folder
    //Load XSL argument list
    XsltArgumentList xslArg = new XsltArgumentList();

    // Transform the file.
    using (XmlWriter w = XmlWriter.Create("output.xml"))
    {
        xslt.Transform("input.xml", xslArg, w);    //located in Debug folder
    }
}

The error is I am not able to load XML file.

The XSL file contains some C# code which is meant to calculate the difference between two DateTime strings .. well, I can transform the XML file manually using the same XSL file .. But when I try to trigger the transformation using C# code .. then it says “It can’t load XML file”

Here is my (part of) XSL code ..

<span bgcolor="#EEEEEE">

   &lt;xsl:variable name="date1" select="//date1"/&gt;
   &lt;xsl:variable name="date2" select="//date2"/&gt;

   &lt;msxsl:script language="C#" implements-prefix="cs"&gt;
   &lt;![CDATA[
         public string datediff(string date1, string date2) {

            DateTime startTime = new DateTime(Convert.ToInt32(date1.Substring(6, 4)), Convert.ToInt32(date1.Substring(0, 2)), Convert.ToInt32(date1.Substring(3, 2)), Convert.ToInt32(date1.Substring(11, 2)), Convert.ToInt32(date1.Substring(14, 2)), Convert.ToInt32(date1.Substring(17, 2)), 0);

            DateTime endTime = new DateTime(Convert.ToInt32(date2.Substring(6, 4)), Convert.ToInt32(date2.Substring(0, 2)), Convert.ToInt32(date2.Substring(3, 2)), Convert.ToInt32(date2.Substring(11, 2)), Convert.ToInt32(date2.Substring(14, 2)), Convert.ToInt32(date2.Substring(17, 2)), 0);

    return(endTime.Subtract(startTime));

         }
     ]]>
   &lt;/msxsl:script&gt;<br>
   &lt;xsl:template match="datediff"&gt;<br>
    &lt;xsl:element name="{local-name()}"&gt;<br>
      &lt;xsl:value-of select="cs:datediff($date1, $date2)" /&gt;<br>
    &lt;/xsl:element&gt;<br>
   &lt;/xsl:template&gt;<br></span>

Is that, because of script(C# code to calculate date diff..) I am getting this error?
By the way C# code runs perfectly when I use some other input XML and XSL files ..

please help me to overcome this error ..

Answer 1

As Steve cooper has mentioned .. you need to enable the XSLT script .. and here is the way to do it:

first define a new settings instance:

var settings = new XsltSettings();

then enable the script

settings.EnableScript = true;

Create the XslCompiledTransform object and load the style sheet, passing in the settings object.
