regex - How can I use regular expression to grab an 'img' tag?

Question

I want to grab an img tag from text returned from JSON data like that. I want to grab this from a string:

<img class="img" src="https://fbcdn-photos-c-a.akamaihd.net/hphotos-ak-frc3/1239478_598075296936250_1910331324_s.jpg" alt="" />

What is the regular expression I must use to match it?

I used the following, but it is not working.

"<img[^>]+src\s*=\s*['"]([^'"]+)['"][^>]*>"

Answer 1

You could simply use this expression to match an img tag as in the example :

<img([wW]+?)/>
