使用SAXON 9.5（的NuGet）使用Schematron

Question

我運行這段代碼：

 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); 

我得到什麼似乎檢查xsltSchematronStylesheet時是一個XSLT文件。然而，st2結尾的流長度爲0。另外，MyMessageListener.Message不接收任何調用（我使用了一個斷點）。

我不知道我是否有壞代碼，壞樣本文件等 我相信我的示例文件是正確的，但也許我有壞的或缺少一些。

有誰知道爲什麼沒有數據返回到流st2。如果不是，你能指導我做一個簡單的樣本，它有所有的文件和作品嗎？

Answer 1

分辨率：

serializer.SetOutputStream(st2); 

應該

serializer2.SetOutputStream(st2); 

Answer 2

我真正的根本問題是尋找簡單完整的示例代碼做的Schematron在.NET。所以對於下一個人來說，這是我正在尋找的樣本。我試圖儘可能地做到這一點。如果我錯過了什麼，請發表評論。

1. 創建單元測試項目
2. 運行的NuGet命令
3. 下載文件Schematron的
4. 使用附帶類和SCH，XML文件。
5. 運行測試程序

的NuGet撒克遜命令行：

Install-Package Saxon-HE 

下載到目前爲止的Schematron文件 http://www.schematron.com/tmp/iso-schematron-xslt2.zip

單元測試：

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

namespace SOAPonFHIR.Test 
{ 
    [TestClass] 
    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); 

     } 
    } 
}

      var compiler = processor.NewXsltCompiler();
