I agree and I'd really rather not parse it myself. However, ET will clean up 
the file which in my case includes some comments required as metadata, so 
that won't work. Oh, I could get ET to read it and write a new parser--I see 
what you mean. I think I need to subclass so I could get ET to honor those 
comments too.
That's one way to go, I was just hoping for something easier.
thanks,
