you might want you want is to "clean" out the stuff between the 'first "word"' and the first | you are in the land of crazy RegEx Voodoo
say something like:
s/[\s\.]+[^\|]*//;
we need to see a "space" or a "." - at least one of them, and then any number of things that are NOT a "|" and we then just RIP them out of the pattern space.
HTH.
