I have a file which contains lots of lines whose values are separated by | ie:

value 1|value 2|tom, chris, dave|value 4
value 1|value 2|peter, tom, dave|value 4

what I want to do is find all the unique names in all the instances of value3 in the file (ie tom, chris, dave & peter).

I know how to do it if the names are in an array but not if they are in an element in an array...

Any suggestions ?

Cheers, Digsy
