The following example uses the XsltMessageEncounteredEventArgs to display xsl:message content to the console. 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();

    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
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()
    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 'Main     
  Private Shared Sub MessageCallBack(ByVal sender As Object, ByVal e As XsltMessageEncounteredEventArgs) 
    Console.WriteLine("Message received: {0}", e.Message)
  End Sub 'MessageCallBack
End Class 'Sample 

The example uses the following files as input:


  <book genre="autobiography" publicationdate="1981" ISBN="1-861003-11-0">
    <title>The Autobiography of Benjamin Franklin</title>
  <book genre="novel" publicationdate="1967" ISBN="0-201-63361-2">
    <title>The Confidence Man</title>
  <book genre="philosophy" publicationdate="1991" ISBN="1-861001-57-6">
    <title>The Gorgias</title>


<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:template match="/">
     <xsl:apply-templates select="*"/>
     <xsl:copy-of select="."/>

  <xsl:template match="*">
     <xsl:apply-templates select="//author"/>

  <xsl:template match="author">
    <xsl:if test="not (last-name)">
       <xsl:message terminate="no">Author name is not in the correct format <xsl:copy-of select="."/>



The XsltMessageEncountered event occurs during XSLT processing when an xsl:message is specified in the style sheet.


If the terminate attribute is set to "yes", the XSLT processor stops executing the style sheet stops after the message is processed.
