Hey all,

So, I'm scrolling through an HTML page, and I'm trying to catch nested tags, i.e., a <span> followed by another <span> before the next </span>.

My question is, if I set up something like:

$i = 0;
while ($html =~ m/</g) {
  # if the next character is the letter 's', $i++
  # if the next character is the forward slash '/', $i--
  # if $i = 1, $temp = everything from < to the next >
  # if $i > 1, do action to get rid of nested loop.  
}

First off, how do I specify 'the next character'? Is something like:
$i = 0;
while ($html =~ m/</g) {
  if ($_ =~ m/$1s/ {$i++;}
  if ($_ =~ m/$1\//) {$i--;}
  if ($i = 1) {$temp = everything from < to the next > }
  if ($i > 1) {do action to get rid of nested loop}
  }

correct?

Secondly, is this how you would do it? Is there a better way?

Thanks
Matt
