Try this:

[^\\]+(?=\.pdf$)

It matches everything except back-slash followed by .pdf at the end of the string.

You can also (and maybe it's even better) take the part you want into the capturing group like that:

([^\\]+)\.pdf$

But how you refer to this group (the part in parenthesis) depends on the language or regexp flavor you're using. In most cases it'll be smth like $1, or \1, or the library will provide some method for getting capturing group by its number after regexp match.

Comments
  • Which language? Some languages have a method to parse URIs in their standard library.
  • I'm skeptical a regex would be faster than getting the index of the last path separator, but I could be wrong.
  • fails: c:\fakepath\some filename with spaces.png
  • Fails if path contains folder names with dots in them.
  • Requirement is filename without extension. You can post a separate question for you needs
  • This worked for related question of mine (file name with extension, but none of the directories -- just add [\w-]*$ after \. -- this also removes issue with having a dot in a folder name).
  • Should it be more like: [^\\](.+)\.pdf$
  • @macduff the question is also the path or just the filename..?
  • I understood it to be the filename, but not the extension or path, sorry if I misunderstood.
  • @KL-7 Thanks, but I don't want the .pdf. I tried using [^\\]+[^.pdf]$ and that concept didn't work
