Hi Andrew,

You need to tell your XMLReader to forward lexical events (e.g. 
comments) to the TransformerHandler as well. In what you have above, you 
have only asked it to forward basic ContentHandler-type SAX events onwards.

Add the following after your setContentHandler() line:

xmlReader.setProperty("http://xml.org/sax/properties/lexical-handler";,
                        hander);

and you should find your comments reappearing.

There's more info in the JavaDoc for org.xml.sax.ext.LexicalHandler

Cheers,
Dave.
