Thanks, not quite sure how to use this in the context of replacing occurrences in a block of text.

Basically this doesn't work:

$text =~ s~(\[img\]\s*.*?\.(?:jpe?g|png|svg|gif|bmp)\s*\[/img\])~Inval
+id~isg;

You want to use Parse::BBCode, but you could try

$text =~ s{
 \[(\w+)\]   # $1 tagname
 ( .*? )     # $2 stuff
 \[\/(\w+)\] # $3 tagname
}{
  TagFudge( $1, $2, $3 );
}gsex;

sub TagFudge {
    my( $open, $content, $close ) = @_;
    if( $content =~ m{\.(jpe?g|gif|xbm|png|bmp)$} ){
        return "Ok";
    } else {
        return "Invalid";
    }
}

But you should use Parse::BBCode

Could't get that to work, it just says everything is invalid.

Right now it's doing the exact opposite of what I want it to!

Yes, and?

"Doesn't work" is not a problem description.

Are you sure $text is what you think it is? You can try to do a print "\n>$text<\n"; and see if it matches your expectations.

If $text is what you think it is, then how doesn't it work? What is your input, what is your expected output, what is your actual output? And with "actual output" I also mean warnings and errors. On that topic, is your script running with use strict; use warnings;?
