Question

I want to find an img tag in a string.
I wrote for example:

var str ='<img border="1" height="165" id="img2" src="http://google.jpg"  />';
var regXstr = "<img (.)*/>";
var regX = new RegExp(regXstr , 'gi');
document.write(str.match(regX));

and the output is the whole text in str which is good in this case, but the if I switch the str with the following:

var str ='<img border="1" height="165" id="img2" src="http://google.jpg" /> /> />';

or with

var str ='<img border="1" height="165" id="img2" src="http://google.jpg"  /><span/>';

the result is still the whole text in str, and I want only the img tag – from <img till first />

You can try making the regex not-greedy using ‘?’:

var regXstr = "<img (.)*?/>";
