Hi Scott,

At the risk of offending the regex gods <GRIN>, I wouldn't use a regex at all...


try:

## return all characters up to the first /  starting from the end 
$desired_path=substr($orig_path,0,rindex($orig_path,'/')+1);

if you _have_ to use a regex, something like:

## all characters up to the first / ([^\/]) starting from the end ($)
$orig_path=~/([^\/]*)$/;
$desired_path=$`;

cheers
