  1. or download this
    s/href\s*=\s*/href=/ig;
    s,(?<!(?i:href=))((?:http|ftp|news)://\S*),<a href="$1">$1</a>,g;
    ...
    You might try to think of something besides '\S*' also, in case
    the user puts in a period after the href, or puts it between
    parenthesis or ???.
    
  2. or download this
    # Now its starting to get ugly!
    $str =~ s#((?i:<a\s+href\s*=\s*"?)?(?:http|ftp|news)://[^"]+)#substr($
    +1,0,1) eq '<' ? $1 : qq!<a href="$1"
    >$1</a>!#eg;
