Will have to look up an explanation of look behind.  I see it on the
cheat sheet I saved from ILoveJackDaniels.com, but haven't investigated
the Assertions purposes yet.

Unless I'm misunderstanding something:

(?:...) passive group which I take to mean, a literal group but please
don't return it.

(?:" target="_new">) should satisfy that requirement.

Have it, but my usual approach to reading only what I need to get the
result I'm looking for isn't paying off as quickly as usual.  RegEx's
are difficult to get.

Thanks again Anthony.  I'll go through all of your provided information
more tomorrow when I'm fresh.
