[Req] Match 1 or more directory path levels

[wammie]

I am looking for a pattern to match 1 or more directory path levels, to replace it with just 1 directory path level.

Examples of directory paths to MATCH (Note - "text with possible spaces between words" refers to unknown text strings, and the number of levels is indeterminate):

http://domain/

http://domain/text with possible spaces between words/

http://domain/text with possible spaces between words/text with possible spaces between words/

http://domain/text with possible spaces between words/text with possible spaces between words/text with possible spaces between words/

REPLACE all matches with http://newdomain/

Another way to express this:

MATCH http://domain/--- anything including "/" or spaces any number of times ---/ (up to the last "/")

REPLACE all matches with http://newdomain/

Thanks to anyone that can help!!
