in thread Regexp: Match anything except a certain word

Thanks! This looks good, although it does not check for http and so it also put the target to local links, but I should be able to put the pieces together now.

    Oops, I read the problem too fast. Fix:
    $test =~ s{ ( <a\s (?:(?!target=|>).)* href="http:// (?:(?!target=|>).)* ) (?=>) }{$1 target="_blank"}xsgi;

    Alternatively, the following *might* be faster, especially considering href is usually the first attribute:

    $test =~ s{ ( <a\s (?:(?!href=|target=|>).)* href="http:// (?:(?!target=|>).)* ) (?=>) }{$1 target="_blank"}xsgi;

    Tested.

    Update: Collapsed (?!..re1..)(?!..re2..) into (?!..re1..|..re2..)
