Using applescript with Filemaker I can make a string of found image
record names such as this:
"1234.jpg, 5678.jpg, 4444.jpg, 5555.jpg, 9876.jpg, 6969.jpg."
What I want to do is delete the last comma and insert an "&" into
the string to make:
"1234.jpg, 5678.jpg, 4444.jpg, 5555.jpg, 9876.jpg & 6969.jpg."
I assume that I use text item deliminators but not sure how as there
are multiple ", " in the string and record names will vary with each
use of the script. Any suggestions?
Regular expressions (best implemented in Satimage.osax) are what you need.
Changing the last comma into " &" with regexp is the following command:
set s to change ",([^,]*)$" into " &\\1" in s
Translation: find a comma (','), followed by a sequence of 0, 1 or
more ('*') characters which can be anything except comma ('[^,]'),
which ends the string ('$'), change that into ' &' followed by the
part of the match that I have encapsulated with parentheses.
For a one-time only job, prefer the text item delimiters method as
presented by kai.
