System.Xml.Xsl: How do I redirect output produced by xsl:message elements to my trace listeners?

I know about Console.SetOut, but can't figure out what I should 开发者_Go百科pass to this method.

Console.SetOut will set stream for console outputs. Use XsltMessageEncountered event of XsltArgumentList class and write the message to Trace listenres using Trace.Write.

void TestTransform()
{
    XsltArgumentList xsltargs = new XsltArgumentList();
    xsltargs.XsltMessageEncountered += new XsltMessageEncounteredEventHandler(OnXsltMessageEncountered);

    XslCompiledTransform transform = new XslCompiledTransform();
    //....some code to load xslt and other stuffs. Pass the xsltargs to transform
}

void OnXsltMessageEncountered(object sender, XsltMessageEncounteredEventArgs e)
{
    //write the message to Trace.
    Trace.Write(e.Message);
}
