Hide all elements with particular number in id
<p>need help, I try to cut complexity and make simple example:</p>

<pre><code>&lt;div id="tree_div"&gt;
   &lt;ul&gt;
      &lt;li id="tree_li_401"&gt;401&lt;/li&gt;
      &lt;li id="tree_li_101"&gt;101&lt;/li&gt;
      &lt;li id="tree_li_301"&gt;301&lt;/li&gt;
      &lt;li id="tree_li_201"&gt;201&lt;/li&gt;
      &lt;li id="tree_li_102"&gt;102&lt;/li&gt;
      &lt;li id="tree_li_402"&gt;402&lt;/li&gt;
   &lt;/ul&gt;
&lt;/div&gt;
</code></pre>

<p>I need to hide all li elements base on <strong>first number after tree_li_</strong></p>

<p>For example: I need to hide all elements which have number <strong>4</strong> after <strong>tree_li_</strong>:</p>

<pre><code>&lt;li id="tree_li_402"&gt;
&lt;li id="tree_li_401"&gt;
</code></pre>
