title: Get src width and height from iframe in variable with javascript
body: <p>hope someone can help me here.
  I have a variable with an iframe in it, like this.</p>
  
  <pre><code>var iframe = '&lt;iframe src="http://someaddress.com" width="600" height="500"&gt;&lt;/iframe&gt;';
  </code></pre>
  
  <p>And i want to get the src, width and height, out of the variable, and into their own variables. I know i can use regular expression to it, but i can´t figure out how.</p>
