How about?
(\w+):([^:]+)?,(\w+):([^:]+)?,(\w+):([^:]+)?
Go to
http://www.organicbit.com/regex/fog0000000019.html and get the regex
tool, it's handy for building these things.
The tool helps when you are coding the regex, but it is cumbersome when you
want to verify the correctness of the regex and match, across a large set of
input. For this you would be better off with a unit test app, where you
store an array of (input,output) pairs. Then run the regex on each input
and compare it to the expected output. (Example below)
-Dino
//
// emailValidation .cs
//
// uses a regexp to validate emails.
// This test program uses xml serialization to get the test input,
// including the regexp string and the various emails to test.

This is input data. Store this in the XML file that is de-serialized for

Can anyone help me figure out a regex pattern for the following input
example:
xxx:a=b,c=d,yyy :e=f,zzz:www:g= h,i=j,l=m
I would want four matches from this:
1. xxx a=b,c=d
2. yyy e=f
3. zzz (empty)
4. www g=h,i=j,l=m
None of the letters here are single letters, but rather placeholders for
arbitrary words. For example,
LTG:LTG=2-41-53-57,JOB:JN=113&& 116&125&&127,CP T:CODE=09789,TR ATYP=AMBINC-7-A MBINC/CPTGRP-0-CPTGRP
Would result in:
1. LTG LTG=2-41-53-57
2. JOB JN=113&&116&125 &&127
3. CPT CODE=09789,TRAT YP=AMBINC-7-AMBINC/CPTGRP-0-CPTGRP
Everything I've come up with so far would require me to iterate over
substrings. It'd be nice to have just a single matching operation. TIA.
