Ok, I'll do.

1) Select a path in any application where text can be selected
2) Go to the application menu and select Services > Open Selected File
3) The file should open in Emacs.app if it exists. If it doesn't, a buffer 
named after the name part of the path is opened.

Problem:

a) if the selected string is not trimmed (for ex you triple-clicked the line 
and it contained leading or trailing ws), the file won't open because the ws is 
considered integral part of the path

b) if the selection contains more than 1 line (for ex. a list of paths on 
multiple lines), no file will open since the whole string is considered the path

What I wrote solves a) and b) by splitting the selected string (except on 
spaces), by trimming the resulting paths, and by looping the original function 
on the thus created list of paths.

The content is an arbitrary string selected in any application that supports 
services. I've removed \s from the delimiters *because* spaces can be part of a 
path on Mac.

Ok, that's something I'll try to do. Thank you.

Create an absolute path like /User/path/to/file or a relative path like 
~/path/to/file, select them and call the service on the selection.

The only issue that I see is when a file name *ends* with (normal) spaces, 
which is unlikely to happen, even if possible.
