How do I search for and select a repeating phrase in a file.

Question

How do I search for and select a repeating phrase in a file read via Applescript. The file contains details of phone calls submitted to a charity and I want to be able to analyse the types of call taken. The phrase is 'Type of enquiry' and I want to extract the description that follows. I am a beginner at Applescript and have been working my way through Applescript 1-2-3 but cannot find an obvious solution although I have manged to open and read the file! All suggestions gratefully received.

Answer 1

In applescript you can use something like the following:
set {oldTID, my text item delimiters} to {my text item delimiters, "Type of enquiry"}
set dataBits to text items of textToParse
set my text item delimiters to oldTID
the variable dataBits, then, will be a list where every list item is a string that starts with the text following that phrase. 
You could do regular expressions searches as well, but you'd need to download and install the Satimage osax.
