title: Regexp match strickly html comment string
body: <p>I'am trying to use regexp to strip all html comments from .html file.
  As we know html comments format are <code>&lt;!-- some comments --&gt;</code>
  I've create such regexp</p>
  
  <p><code>/&lt;!--.*--&gt;/gs</code></p>
  
  <p>It works, but if there is more than one comment block in file, it strips no one to another block, but all from first <code>&lt;!--</code> to last <code>--&gt;</code>
  F.e.</p>
  
  <pre><code>some html tags
  &lt;!-- some comments 1 --&gt;
  some html tags 2
  &lt;!-- some comments 2--&gt;
  </code></pre>
  
  <p>It strips entire </p>
  
  <pre><code>&lt;!-- some comments 1 --&gt;
  some html tags 2
  &lt;!-- some comments 2--&gt;
  </code></pre>
  
  <p>I'am code with ActionScript language.
  Any advice would be helpful.
  Thanks!</p>
