Regular expression for counting sentences in the text escaping the dot in email adress

I have a sentence like My email address is xxxx@xxx.xxx.

My java regExp is ".+?[\.\?\!]+" This regExp sees two sentences My email addre开发者_开发问答ss is xxxx@xxx. and xxx.

How do i modify my regExp so it wouldn't count email dots as a sentence end?

You can't reliably. Consider this example:

My email is someone@subdomain.com.hi!

Is the email someone@subdomain.com.hi or just someone@subdomain.com?

The only thing you can do is, if your texts are written by literate people, detect a sentence ending as one of ., ?, ! (or maybe other) plus some space.

And now to ruin all hope. What about this text? How many sentences does it have?

He shouted "Freeze!", and then pulled out his gun.

---

With proper writing, that is - leaving space after each punctuation mark, you can look for each \.\s

---

Decide what constitutes the end of a sentence, I'd probably use a '.' followed by space, tab or end of line.

---

Actually I am not clear about your question. If you are looking for a regular expression for detecting valid e-mail address use this.

pattern=/^[a-zA-Z0-9_-.]+@[a-zA-Z0-9_-.]+\.[a-zA-Z]{2,4}$/

Example:

• name@gmail.co.uk
• name1.name2@gmail.com
• name1_name2@hotmail.co.ir
• etc.
