iOS: Get Image From HTML String

Question

I have an application that is pulling articles from the web and I need to retrieve the URL for the first image in an article. Here's an example of the code for these images:

<img alt="Twitter (zpower)" src="http://www.example.com/image.png" width="630" height="420">

I need to get just the value for the src. How would I do this?

You'll need to parse the HTML and extract the src attribute. You could do it by hand, but a better way is to rely on someone else's parsing library (for instance, ElementParser).

I'd like to second @ravuya's response, but also mention that you can also use the built in NSXMLParser to do the parsing for you.
