正则表达式可选字符[关闭]

Question

The 3 strings (here are HTML codes, please don't say use HTML parsers, I have to use RegEx):

</div><img src="http://www.example.com/nano.png" alt="NANOTECH" />
</div><img src="http://www.example.com/internet.gif" alt="INTERNET" />
</div>

I want to capture there 3 lines. So tried this: (PHP preg_match)

<\/div>.[<img src="http:\/\/www.example.com\/.*?\/>]+

But it gets just </div><img src="http://www.example.com/

What's wrong?

Answer 1

You need round brackets, not square ones. Square brackets denote a character class, which matches any single character of the ones in the brackets. You also don't want the dot between /div> and <img, since there's no gap between them in your examples.
