in thread Deleting elements of one list using another

You mean $splitted[0]? :)
But no. splitted[0] contains "John" in the first loop, than "Jane", finally "Jessica". You'd like to grep the whole "John ABC 42" for ABC, don't you?
Otherwise I haven't understand the problem well enough.

I'm too lazy to be proud of being impatient.
