Let's say you have some html like this:

<b>I like</b> <i>squirrels!</i>.
[download]

You could use this:

$html =~ s/<[^>]*>([^<]*)<\/[^>]*>/$1/gs;
[download]

To turn it into this:

I like squirrels.
[download]

{QandAEditors note: merlyn points out by way of followup that the above regexp only works for simple HTML, and that in real life HTML, the regexp can't be counted upon to not fail. See the followup for details. }

Sure, that works for simple HTML, but real life HTML can fail on such a simple regex. For example: `<!-- > this is still the comment --> and some more text` [download] In that case, "this is still the comment" would be left within the output, when it shouldn't be. -- Randal L.
