That works just fine for me.  Here's a transcript:

/home/erics$ perl    
@content  = ('abc', 'def', '', 'fgh', 'ijk');
foreach $i (@content) {
   next if ($i =~ /^$/);

   print "\$i = [$i]\n";
}
^D
$i = [abc]
$i = [def]
$i = [fgh]
$i = [ijk]
/home/erics$

You could try using a label ("foo: foreach (...) { next foo; }"), I
suppose, but I have a feeling $i may not be as empty as you think it is.
I see you're printing it out with delimiters, so I'm kind of at a loss as 
to what the actual problem might be. :-\
