Usando Saxon 9.5 (Nuget) con schematron

Question

Sto eseguendo questo codice:

        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);

.

ottengo ciò che sembra essere un file XSLT quando esami XSLTScheMatronStylesheet.Tuttavia il flusso alla fine ST2 ha una lunghezza 0.Inoltre, MymessaGelistener.Message non riceve chiamate (ho usato un punto di interruzione).

Non sono sicuro se ho un codice cattivo, i cattivi file di esempio, ecc. Credo che i miei file di esempio siano corretti, ma forse ho cattivi o mi manca un po '.

Qualcuno sa perché nessun dato viene restituito al flusso ST2.Se no no puoi indirizzarmi ad un buon esempio semplice che ha tutti i file e funziona?

Answer 1

Il mio vero problema sottostante stava trovando un semplice codice di esempio completo per fare schematron in .NET.Quindi per il prossimo ragazzo qui è il campione che stavo cercando.Ho provato a renderlo il più completo possibile.Se mi mancassi qualcosa, lascia un commento.

.
1. Creare un progetto di test unitario
2. Esegui il comando Nuget
3. Scarica i file schematron
4. Utilizzare le classi incluse e i file XML.
5. Esegui il programma di test

Commandline della Nuget Saxon:

Install-Package Saxon-HE 

.

Scarica File schematron aggiornati http://www.schematron.com/tmp/iso-schematron-xslt2.zip .

using Microsoft.VisualStudio.TestTools.UnitTesting;
using System.IO;

    public class Schematron
    {
        [TestMethod]
        public void XSLT_SAXON_Simple_Schematron2()
        {

            ///////////////////////////////
            // Transform original Schemtron  
            ///////////////////////////////
            string path = AppDomain.CurrentDomain.BaseDirectory;

            Uri schematron = new Uri(@"file:\\" + path + @"\simple\input.sch");
            Uri schematronxsl = new Uri(@"file:\\" + path + @"\xsl_2.0\iso_svrl_for_xslt2.xsl");

            Stream schematrontransform = new Test.XSLTransform().Transform(schematron, schematronxsl);

            ///////////////////////////////
            // Apply Schemtron xslt 
            ///////////////////////////////
            FileStream xmlstream = new FileStream(path + @"\simple\input.xml", FileMode.Open, FileAccess.Read, FileShare.Read);
            Stream results = new Test.XSLTransform().Transform(xmlstream, schematrontransform);

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

        }

Answer 2

Risoluzione:

serializer.SetOutputStream(st2);

.

dovrebbe essere

serializer2.SetOutputStream(st2);
