 I should have made a note about what it did. I *think* it's actually a
 conditional, checking whether group 4 was used and then looking for the
 end tag only if its not self closing.

 According to http://www.regular-expressions.info/conditional.html,
 conditionals are supported in pcre. Not sure if that helps?

 "Conditionals are supported by the JGsoft engine, Perl, PCRE and the .NET
 framework."
