How to apply an XSLT Stylesheet in C#

I want to apply an XSLT Stylesheet to an XML Document using C# and write the output to a File.

Edit:

@Rob Cooper: Yes, I am aware of that. But I couldn't find it in SO. The Idea of this site is to collect answers to any question a developer could have, right? I had this question today and thus posted an answer. Next time I look (this is not the first time I forgot the actual classes to use) I will know where to find the answer - StackOverflow.

Is this clogging up? I don't really think so...

• I found a possible answer here: http://www.csharpfriends.com/Articles/getArticle.aspx?articleID=63

  From the article:

  XPathDocument myXPathDoc = new XPathDocument(myXmlFile) ;
  XslTransform myXslTrans = new XslTransform() ;
  myXslTrans.Load(myStyleSheet);
  XmlTextWriter myWriter = new XmlTextWriter("result.html",null) ;
  myXslTrans.Transform(myXPathDoc,null,myWriter) ;
  

  Edit:

  But my trusty compiler says, XslTransform is obsolete: Use XslCompiledTransform instead:

  XPathDocument myXPathDoc = new XPathDocument(myXmlFile) ;
  XslCompiledTransform myXslTrans = new XslCompiledTransform();
  myXslTrans.Load(myStyleSheet);
  XmlTextWriter myWriter = new XmlTextWriter("result.html",null);
  myXslTrans.Transform(myXPathDoc,null,myWriter);
  

  AJ : Works like a charm. You should mark this as the answer.

  Daren Thomas : done. feel a bit funny accepting my own answer, though...

  just as a side note: if you want to do validation too here is another tutorial (for DTD, XDR, and XSD (=Schema)):
