XsltMessageEncounteredEventArgs Class
Provides data for the XsltMessageEncountered event.
Assembly: System.Xml (in System.Xml.dll)
The XsltMessageEncountered event occurs during XSLT processing when an xsl:message is specified in the style sheet.
Note: |
|---|
If the terminate attribute is set to "yes", the XSLT processor stops execution of the style sheet stops after the message is processed. |
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>.

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 '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
