If you've got anything beyond the most trivial
cases for parsing data with nested elements,
you are probably best off using an appropriate
parsing module (eg Parse::RecDescent).
If you've got nesting going on but you are ready
for some pretty advanced perl regex tricks, you
can try patterns that contain a recursive call to
themselves.
To quote from Camel 3rd edition, p213-214 (where
I got an awful lot of my latest knowledge of cool perl
idioms):
Any text on regular expressions will tell you
that a standard regex can't match nested
parentheses correctly. And that's correct.
It's also correct that Perl's regexes aren't
standard.
