"\n"; } else { print $_; } } else { print $_; } } This is a somewhat simplistic implementation; for instance, it assumes that there won't be more than one <telephone> on a single input line, and it doesn't scale well for multiple clients that you're filtering out. It also assumes no CDATA marked sections, and demonstrates why </> makes the DPH's life impossible. I haven't actually run this, but it's similar enough to other things I've done that I think it should work. -Chris -- <!NOTATION SGML.Geek PUBLIC "-//Anonymous//NOTATION SGML Geek//EN"> <!ENTITY crism PUBLIC "-//O'Reilly//NONSGML Christopher R.
