title: Regex: Trying to grab text inside quotes
body: <p>I have this string</p>
  
  <p><code>&lt;img class="img-thumbnail thumb" style="width:100px;height:100px;" src="data:image/png;base64,/9j/4AAQMCgsOCwkJDRENDgBAQjKv+I1atf2Q==" class="img-thumbnail thumb" style="width:100px;height:100px;"</code></p>
  
  <p>and I just want to grab 
  <code>data:image/png;base64,/9j/4AAQMCgsOCwkJDRENDgBAQjKv+I1atf2Q==</code></p>
  
  <p>I've tried multiple attempts on regexr. I'm a bit stuck and so far I have 
  src="(.*)". I'm not sure how to get it to stop at that next quote.</p>
