Dear Developer,
I need your help on this please.
That I want to extract data from text file after specific word.
Sample data in text file as below, I want only data after “Message Content:” and end of “End content.”

e.g.

Message Content:

ISA^00^ ^00^ ^01^003897733EPXRI ^01^KMNPROD ^220510^0302^U^00602^000054481^0^P^]
