Regular expression problem

[Asheesh Laroia]

Actually, I think this is the most elegant solution I've seen so far.

Good thinking; I forgot to "Use the Source," as some put it.

Only one problem: the parser still balks on embedded tags, like:

	<@Trap Body text:<P><I><B>>
becomes
	>

It leaves an extra '>' character at the end.  Any suggestions?  I can
write a simple workaround for something like this, but it seems like
it should work "the right way."

Thanks for everything!
