Question

I need to extract http links from a set of text information. Particular phrases which has image extenstions(.jpg, .png)

For example, I want alone “http://www.mywedding.com/blog/wp-content/gallery/p_867/bridal-party-white-flowers-40306.jpg”

from the below set of thing

 <p><a href="http://www.mywedding.com/blog/wp-content/gallery/p_867/bridal-party-white-flowers-40306.jpg" target="_blank"><a href="http://www.mywedding.com/blog/wp-content/gallery/p_867/bridal-party-white-flowers-40306.jpg">http://www.mywedding.com/blog/wp-content/gallery/p_867/bridal-party-white-flowers-40306.jpg</a></a> (from <a href="http://cameroningalls.com/emily-meeko-tiburon/" target="_blank">this wedding by Cameron Ingalls</a>)</p>

If those are img tags, i can get it from simple appraoch

String s="<img src="https://i.stack.imgur.com/SUSRH.jpg"/> 

s=s.replace("<img src=", "");
s=s.replace("/>", "");

But I am confused to get through first scenario, Any suggestions for it?

Do you already have the raw information in a single string? This looks like a classic job for regular expressions. I would check this site,

And there’s a pretty good explanation of how to use it here:
