Pera, que aun queda mecha XDDD

$cad= "<info>prueba1234<kk>delavaca</kk></info><info>blablablabla</info>";
$cad=~ s/<info>(.*?)<\/info>.*/$1/;
print "$cad\n";

El (.*?) lo he sacado de la pagina del perlre
  http://www.perldoc.com/perl5.6.1/pod/perlre.html#Backtracking

Copy-paste:

Here it's more effective to use minimal matching to make sure you get the
text between a "foo" and the first "bar" thereafter.

    if ( /foo(.*?)bar/ ) { print "got <$1>\n" }
      got <d is under the >  

A ver que tal te va :D
