get text, and split it after a given string
<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>
