White space cannot be stripped from input documents that have already been loaded. Provide the input document as an XmlReader instead

Question

I want to transform a XML document, but having a problem.

My XSLT looks like this:

Answer 1

I solved it. Actually "XslCompiledTransform.Transform" takes XmlReader as first Parameter and i was passing XmlDocument in First Paramenter. Here is the code.

public static string Transform(XmlDocument doc, XmlDocument stylesheet)
    {
        try
        {
            System.Xml.Xsl.XslCompiledTransform transform = new System.Xml.Xsl.XslCompiledTransform();
            transform.Load(stylesheet); // compiled stylesheet
            System.IO.StringWriter writer = new System.IO.StringWriter();
            XmlReader xmlReadB = new XmlTextReader(new StringReader(doc.DocumentElement.OuterXml));
            transform.Transform(xmlReadB, null, writer);
            return writer.ToString();
        }
        catch (Exception ex)
        {
            throw ex;
        }

    }
