Re: Regex: Matching last of repeated character to end of string

[radiantmatrix]

There are three approaches I can think of that would solve your issue, and only one is a regex.

1. The regex solution:

   $xpath =~ s{/[^/]+$}{};
   

2. The split solution:

   my @temp = split('/', $xpath);
   $xpath = join('/',@temp[0..$#temp-1]);
   

3. The rindex solution:

   $xpath = substr($xpath,0,rindex($xpath,'/'));
   

The last one (rindex) strikes me as the most efficent way to go, but I haven't Benchmarked it.

Or even substr($xpath, rindex($xpath, '/')) = "";!
