Script to extract delimited info from a text file?

Scripting Forums AppleScript | Mac OS X
#1

Hello. I have a very long txt file that has quite a few pieces of information that I would like to extract and then a bunch of other useless text. The information I would like is always preceded by “file/?qwe=” and is always followed by “”. Can anyone help me with a script that would extract the info I want or remove everything else?
Thank you,
Erik

Hi,

If the file is too big (number of characters) or the list is too long you might get an error, but something like this:


set the_file to choose file
set the_text to read the_file
set tids to AppleScript's text item delimiters
set AppleScript's text item delimiters to {"1A"}
try
	set text_items to rest of (text items of the_text)
	set item_list to {}
	repeat with this_item in text_items
		set AppleScript's text item delimiters to {"2A"}
		set item_list to item_list & first text item of this_item
	end repeat
	set AppleScript's text item delimiters to tids
on error error_msg
	set AppleScript's text item delimiters to tids
	display dialog error_msg
	return
end try
return item_list

It’s been a while since I’ve written scripts but this seems to work.

You then do with the resulting list whatever.

gl,

Editted:

replace the “A1” and “A2” strings with your delimiters.
