Re^4: Grabbing url from iframe

Thanks for this. Here's what I have:

$video =~ s/
   (<iframe
   [ ]title="YouTube[ ]video[ ]player"
   [ ]width=")([0-9]+)("
   [ ]height=")([0-9]+)("
   )
/
   $1 . "320" . $3 . ( (320/$2)*$4 ) . $5
/xeg;
[download]

But it's returning this error:

Scalar found where operator expected at mobile.pl line 296, near "$1 .
+ "320" . $3 . ( (320/$2"
  (Might be a runaway multi-line // string starting on line 289)
        (Missing operator before $2?)
syntax error at mobile.pl line 296, near "$1 . "320" . $3 . ( (320/$2"
[download]

Am I missing something?

You delimit your regular expression using `/`, but the replacement part also contains a `/`. That's unfortunate. Use a different separator for the regular expression, for example `!`: `$video =~ s!... !... !xeg;` [download]	[reply] [d/l] [select]

You're exactly right. That did it. Thanks so much. This was over my head but that worked! Can someone explain what this last line does. I sort of get it, but not really. `$1 . "300" . $3 . ((300/$2)*$4) . $5` [download]	[reply] [d/l]

Maybe it's now time to learn Perl operators. See perlop for what the operators do.	[reply]
