title: Extract images links from javascript img tag in HTML files in java
body: <p>I'm using apache tika parser for parsing html files and tika extracts images links inside img tags such as below:</p>
  
  <pre><code>&lt;img ....some variables... src="http://some image.jpg" ....some variables...&gt;
  </code></pre>
  
  <p>but it could not extract images links such as:</p>
  
  <pre><code>&lt;img ....some variables... image-src="http://some image.jpg" ....some variables...&gt;
  </code></pre>
  
  <p>or:</p>
  
  <pre><code>&lt;img ....some variables... data-original="http://some image.jpg" ....some variables...&gt;
  </code></pre>
  
  <p>or some other variables insted of "src".
  Is it possible to extract such these images links in java?</p>
