Subject: Re: Perhaps a little over complicated - Dissecting a String
These are all good steps in the right direction however, I haven't found
anything that ties all this logic together.
Logic
if first sentence is between 200-250 characters show that setence
if no sentence, show first 250 characters +...
if first sentence is less than 250 sentences, get as many sentences as
possible before hitting 250 characters and output.
Has anyone built something like this?
Thanks
