Question

Im trying to use a regex in javascript to add a line break after every sentence to json data that is being formatted as an html variable.

Locating it based just on the period wasnt working — there seemed to be extra characters in the json data or something else that was causing line breaks every 3 or 4 words.

So Im trying to search for a period with the look-ahead for a capital letter. But this is adding the line break before every capital letter, not just ones that follow a period.

Im pretty new to regular expressions so any help would be very very helpful!

Right now the search parameter for the period followed by a capital letter is: /.(?=[A-Z])/g

The javascript is: description.replace(/.(?=[A-Z])/g, '<br /><br />');

Answer 1

Couple of issues.
First . in RegExp means, “any character”.
Second, I don’t think you need the ?=. I think you’re probably looking for something like this:

 /\.(\s+)[A-Z]/g
