title: get text, and split it after a given string
body: <p>is there any javascript method to get text, and split it after a certain value? </p>
  
  <p>Like for instance, having: </p>
  
  <pre><code>&lt;p&gt;here is some text &lt;!-- read more --&gt; and here is some more&lt;/p&gt;
  </code></pre>
  
  <p>get this:</p>
  
  <pre><code>&lt;p&gt;here is some text&lt;/p&gt; &lt;p&gt;and here is some more&lt;/p&gt;
  </code></pre>
  
  <p>I suppose jQuery don't have the tools to achieve this.</p>
