Does this match your expectations? 

$s = '<COMMA>pre-stuff<EXHIBITING>some stuff</EXHIBITING>post-stuff</C
+OMMA>';;

print "$1 :: $2" while $s =~ s[<(\D+)>([^<]*?)</\1>][]gi;;
EXHIBITING :: some stuff
COMMA :: pre-stuffpost-stuff

Of course, it fails horribly if your non-tag content contains '<':

$s = '<COMMA>pre-stuff<EXHIBITING>some <= stuff</EXHIBITING>post-stuff
+</COMMA>';;

print "$1 :: $2" while $s =~ s[<(\D+)>([^<]*?)</\1>][]gi;;
{zilch here}

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
