regular expression to match everything until the last occurrence of /

Question

Using a regular expression (replaceregexp in Ant) how can I match (and then replace) everything from the start of a line, up to and including the last occurrence of a slash?

Answer 1

What you want to do is match greedily, the longest possible match of the pattern, it is default usually, but match till the last instance of '/'.

That would be something like this:

 .*\/

Explanation:

. any character
* any and all characters after that (greedy)
\/ the slash escaped, this will stop at the **last** instance of '/'
