Regex are not my favorite part of Perl....even if they are powerful. I'm trying to use your way to detect if a string is base64...so I was taking what you had and putting an if around it. I'm sure I'm just not getting it....could you give me some pointers? 

if($string_whole =~ m 
/
    ^ 
    (?: [A-Za-z0-9+/]{4} )*
    (?: [A-Za-z0-9+/]{2} [AEIMQUYcgkosw048] = 
    |   [A-Za-z0-9+/] [AQgw] ==
    )?
    \z
/x
) $&Log ("it found base64-$i");

Thanks in advance for your expertise.
