Regular expression matching sentence

Question

I need regular expression which would match a sentence in a text file. By sentence I mean a string which starts with capital letter and ends with a period. So far I've came up with this:

[A-Z]+[A-Za-z0-9_,"#;.() \t]+[.]$

It's kind of working, but there's a little problem. When there are few sentences in one line, it sums them up and count as one. Any tips how to fix it?

Answer 1

I would extend this to [A-Z][\s\S]+?[.?!]+. "LOOK OUT!!" is a sentence in my book. Also allows for sentences with whitespace between them.

Answer 2

You could try this regular expression

[A-Z]{1}[^.]*.
