Trimming a string after last instance of / character

2004-03-02 Thread Richard Crawford 
Given a string that contains a directory name (e.g., 
/var/www/html/files/classes/admin), what is the best way to trim all 
of the characters off the last instance of the / character?

Treat the string like a slash-delimited list, and use the appropriate 
function (someone borrowed my cf reference, sorry) to delete the last 
item.Something like (but probably not actually)

listdeleteat(string, listlen(string, '/'), '/');

 listdeleteat(string, listlen(string, '/'), '/');

Or

getDirectoryFromPath(string)

That's very close to what I need.I need to ascend one directory level 
and then descend into a different directory.

From:

/directory/subdirectory/path1

to:

/directory/subdirectory/path2

Re: Trimming a string after last instance of / character - RESOLVED

This is what I used:

cfset pathDir=#GetDirectoryFromPath(CGI.PATH_TRANSLATED)#
cfset trimpathDir=listdeleteat(#pathDir#, listlen(#pathDir#,'/'), '/') 
 /

Adding the final / at the end turned out to be key.
