in reply to Selecting HL7 Transactions

better try [^|] instead of .

PV1\|1\|O\|([^|]*?\|){3}\|

do you really need to capture field 2-5 ?

Honestly this code hurts my eyes and horrifies my senses for maintenance !

Better consider something like putting your first regex in a while loop and analyzing the captured string within that loop.

Friedl's book is a good read!

[hippo]: Try it and see. Your computer won't explode.
[Corion]: length will tell you the length of a string.
[Corion]: But if you are parsing CSV, again, let me point to Text::CSV_XS, which you should use instead
[hippo]: +1 for Text::CSV_XS
[ovedpo15]: Im not allowed to use additional modules, so I can't use it. looking for a simple regex to do this task though..
[Corion]: Ah, so this is homework? Then most likely, you should review your course material closer. It would greatly surprise me if the course material wouldn't mention the topics that will be used in the homework...
[Corion]: I already showed you the simple regex to match the last part of a string without a comma in it
[Tux]: Corion++ hippo++
