示例

下面的示例使用XsltMessageEncounteredEventArgs将内容显示xsl:message到控制台。The following example uses the XsltMessageEncounteredEventArgs to display xsl:message content to the console. 该示例将以下消息写入控制台: Message received: Author name is not in the correct format <author><name>Plato</name></author>The sample writes the following message to the console: Message received: Author name is not in the correct format <author><name>Plato</name></author>.

using System;
using System.IO;
using System.Xml;
using System.Xml.Xsl;
using System.Xml.XPath;

public class Sample {

  public static void Main() {

    // Create the XslCompiledTransform object and load the style sheet.
    XslCompiledTransform xslt = new XslCompiledTransform();
    xslt.Load("message.xsl");

    XsltArgumentList argList = new XsltArgumentList();
    argList.XsltMessageEncountered += new XsltMessageEncounteredEventHandler(MessageCallBack);
    
    // Load the file to transform.
    XPathDocument doc = new XPathDocument("books.xml");

    // Transform the file.
    xslt.Transform(doc, argList, XmlWriter.Create("output.xml"));

  }

  private static void MessageCallBack(object sender, XsltMessageEncounteredEventArgs e) {
    Console.WriteLine("Message received: {0}", e.Message);
  }

}
Imports System.IO
Imports System.Xml
Imports System.Xml.Xsl
Imports System.Xml.XPath

Public Class Sample    
    
  Public Shared Sub Main() 
        
    ' Create the XslCompiledTransform object and load the style sheet.
    Dim xslt As New XslCompiledTransform()
    xslt.Load("message.xsl")
        
    Dim argList As New XsltArgumentList()
    AddHandler argList.XsltMessageEncountered, AddressOf MessageCallBack
        
    ' Load the file to transform.
    Dim doc As New XPathDocument("books.xml")
        
    ' Transform the file.
    xslt.Transform(doc, argList, XmlWriter.Create("output.xml"))
    
  End Sub
    
  Private Shared Sub MessageCallBack(ByVal sender As Object, ByVal e As XsltMessageEncounteredEventArgs) 
    Console.WriteLine("Message received: {0}", e.Message)
    
  End Sub
End Class

该示例使用以下文件作为输入:The example uses the following files as input:
