Re: Stripping the contents of Javascript tags

You're probably experiencing greed. This means the .* in the middle of your match will grab everything between the first <script> and last </script> in $foo, including other </script>...<script> combinations.

The following code should give you some ideas. It does assume that there are no other HTML tags between the <script> and </script> tags.

$s = qq(<script>chunk1</script> stuff <Script>chunk2</Script>);
while ( $s =~ m|<script>([^<]+)<\/script>|gi ) {
   print "match: $1\n";
}

Also, I don't know if this was intentional or not, but you're also doing a substitution by starting your expression with an s. That will replace anything you match in $foo with nothing (effectively removing it from the scalar).

I hope this is what you were looking for.

`It does assume that there are no other HTML tags between the <script> and </script> tags.` [download] Er, no it doesn't -- it assumes there are no HTML open-brackets inside the script tags, and as they are also the less-than signs, that's a fatally flawed assumption. Any JavaScript for-loop will kill that regex. -- “Every bit of code is either naturally related to the problem at hand, or else it's an accidental side effect of the fact that you happened to solve the problem using a digital computer.” M-J D	[reply] [d/l]

This means the . in the middle of your match. . . Uhm... that `.` looks an awful lot like a `.*?` to me. ;-) -sauoq "My two cents aren't worth a dime.";	[reply]

Ack! Sorry about that. I guess a little knowledge really can be dangerous. Thanks for letting me know where I went wrong.	[reply]
