Strip file path info to • and / text item delimiter - applescript

Question

The script below basically you choose a folder with PDFs, get file count of PDFs on chosen folders, write the results in text file, open the text file in Excel. The scripts works fine but I get entire the file path.
Results are:
/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/BODY/: 65
/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/BODY/: RESENDS 0
/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/COVERS/: 23
/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/COVERS/: RESENDS 6
I want to strip everything before the bullet • then for every / a column. Something like this:
CUSTO_4 BODY 65
CUSTO_4 BODY RESENDS 0
CUSTO_4 COVERS 23
CUSTO_4 COVERS RESENDS 6
I trying to grasp the concept of text item delimiters and using the offset command but I don't know how to implement that into the script.
set target_folder to choose folder with prompt "Choose target folders containing only PDFs to count files" with multiple selections allowed without invisible
set results to ""
repeat with i from 1 to (count target_folder)
set thisFolder to (POSIX path of item i of target_folder)
--Find & count all PDFs in folders selected that DON'T starts with letter R
set fileCount to do shell script "find " & quoted form of thisFolder & " -type f -name *.pdf -and -not -iname 'R[0-9-_]*.pdf' | wc -l"
set results to (results & "" & thisFolder & ":" & fileCount & return)
--Find & count all PDFs in folders selected that starts with letter R
set fileCount to do shell script "find " & quoted form of thisFolder & " -type f -iname 'R[0-9-_]*.pdf' | wc -l"
set results to (results & "" & thisFolder & ":" & tab & tab & "RESENDS" & fileCount & return)
end repeat
--write results to a txt file
set theFilePath to (path to desktop folder as string) & "PDF File Count.txt"
set theFile to open for access file theFilePath with write permission
try
set eof of theFile to 0
write results to file theFilePath
close access theFile
on error
close access theFile
end try
--Will open the the PDF File Count.txt in Excel
tell application "Microsoft Excel"
activate
open text file filename "PDF File Count.txt"
end tell

AppleScript's text item delimiters are used to determine how text is broken apart and/or reassembled. When you get the text items of a string, the string is broken apart at each delimiter, and the result is a list of the pieces. Going the other way, if you coerce a list of text items to a string, the pieces are reassembled with the delimiter used in between each piece.
For your example, you could use something like the following (I added a little formatting to get your result):
set theList to {¬
"/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/BODY/: 65", ¬
"/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/BODY/: RESENDS 0", ¬
"/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/COVERS/: 23", ¬
"/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/COVERS/: RESENDS 6"}
set finalResult to {} -- this will be the final result
set tempTID to AppleScript's text item delimiters -- stash the original delimiters
repeat with anItem in theList
set AppleScript's text item delimiters to "•"
set pieces to text items of anItem -- break apart at bullets
log result
set theFile to (rest of pieces) as text -- drop the first piece and reassemble
set AppleScript's text item delimiters to "/"
set pieces to text items of theFile -- now break apart at slashes
log result
set lastPiece to last item of pieces -- trim the last piece a bit
set theCount to 0
repeat while first character of lastPiece is in {space, ":"}
set lastPiece to text 2 thru -1 of lastPiece -- trim it
set theCount to theCount + 1 -- count up trimmed characters
end repeat
if theCount > 4 then set lastPiece to tab & tab & lastPiece -- add a little formatting...
set last item of pieces to lastPiece -- put the trimmed piece back
set text item delimiters to tab & tab
set pieces to pieces as text -- put the pieces back together with tabs
log result
set end of finalResult to pieces -- store the reassembled text for later
end repeat
set AppleScript's text item delimiters to tempTID -- restore the original delimiters
choose from list finalResult with empty selection allowed -- show the results

You don't always have to use text item delimiters to manipulate text:
set xxx to "/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/BODY/: 65
/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/BODY/: RESENDS 0
/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/COVERS/: 23
/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/COVERS/: RESENDS 6"
set yyy to do shell script "echo " & quoted form of xxx & " | grep -o •.* | sed -e 's/•\\(.*\\):\\(.*\\)/\\1\\2/' -e 's/\\// /'g"
and the other approach:
set xxx to "/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/BODY/: 65
/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/BODY/: RESENDS 0
/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/COVERS/: 23
/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•CUSTO_4/COVERS/: RESENDS 6"
-- break apart and capture original delimiters
set {Astid, AppleScript's text item delimiters} to {AppleScript's text item delimiters, "/Volumes/PREPRESS/1_CATALOG/2_Press/PRINT_Catalog/2012/•"}
set yyy to text items 2 thru -1 of xxx
--put together
set AppleScript's text item delimiters to {""}
set yyy to yyy as string
-- break apart
set AppleScript's text item delimiters to ":"
set yyy to text items of yyy
--put together
set AppleScript's text item delimiters to {""}
set yyy to yyy as string
-- break apart
set AppleScript's text item delimiters to "/"
set yyy to text items of yyy
--put together
set AppleScript's text item delimiters to tab
set yyy to yyy as string
-- reset original delimiters
set AppleScript's text item delimiters to Astid
return yyy
