Using SAXON 9.5 (nuget) with Schematron

Question

I am running this code:

        string path = AppDomain.CurrentDomain.BaseDirectory;

        // Uri schemaUri = new Uri(@"file:\\" + path + @"\sch\patient.sch");
        Uri totransformEE = new Uri(@"file:\\" + path + @"\po\po-schema.sch");
        Uri transformER = new Uri(@"file:\\" + path + @"\xsl\conformance1-5.xsl");

        ///////////////////////////////
        // Crate Schemtron xslt to be applied
        ///////////////////////////////
        // Create a Processor instance.
        Processor processor = new Processor();

        // Load the source document
        XdmNode input = processor.NewDocumentBuilder().Build(totransformEE);

        // Create a transformer for the stylesheet.
        XsltTransformer transformer = processor.NewXsltCompiler().Compile(transformER).Load();

        // Set the root node of the source document to be the initial context node
        transformer.InitialContextNode = input;

        // Create a serializer
        Serializer serializer = new Serializer();
        MemoryStream st = new MemoryStream();
        serializer.SetOutputStream(st);

        // Transform the source XML to System.out.
        transformer.Run(serializer);

        st.Position = 0;
        System.IO.StreamReader rd = new System.IO.StreamReader(st);
        string xsltSchematronStylesheet = rd.ReadToEnd();

        System.Diagnostics.Debug.WriteLine(xsltSchematronStylesheet);

        // Load the source document
        Uri transformEE2 = new Uri(@"file:\\" + path + @"\po\po-bad.xml");

        var documentbuilder2 = processor.NewDocumentBuilder();
        XdmNode input2 = documentbuilder2.Build(transformEE2);

        ////// Create a transformer for the stylesheet.
        StringReader sr2 = new StringReader(xsltSchematronStylesheet);
        XsltTransformer transformer2 = processor.NewXsltCompiler().Compile(sr2).Load();

        // Set the root node of the source document to be the initial context node
        transformer2.InitialContextNode = input2;

        // Create a serializer
        Serializer serializer2 = new Serializer();
        MemoryStream st2 = new MemoryStream();
        serializer.SetOutputStream(st2);

        transformer2.MessageListener = new MyMessageListener();
        // Transform the source XML to System.out.
        transformer2.Run(serializer2);

        st2.Position = 0;
        System.IO.StreamReader rd2 = new System.IO.StreamReader(st2);
        string xsltSchematronResult = rd2.ReadToEnd();
        System.Diagnostics.Debug.WriteLine(xsltSchematronResult);

I get what appears to be an XSLT file when examining xsltSchematronStylesheet. However the stream at the end st2 has 0 length. Also, MyMessageListener.Message receives no calls (I used a break point).

I am not sure if I have bad code, bad sample files, etc. I believe my sample files are correct, but maybe I have bad ones or am missing some.

Does anyone know why no data is returned to the stream st2. If not can you direct me to a good simple sample that has all the files and works?

Answer 1

Resolution:

serializer.SetOutputStream(st2);

should be

serializer2.SetOutputStream(st2);
