Jquery search multidimensional ul list
<p>I have next HTML:</p>

<pre><code>  &lt;input type="text" id="search" name="searchword" value="" /&gt;
&lt;ul id="search_list"&gt;
    &lt;li&gt;first&lt;/li&gt;
    &lt;li&gt;second&lt;/li&gt;
    &lt;li&gt;third
        &lt;ul&gt;
            &lt;li&gt;aaa&lt;/li&gt;
            &lt;li&gt;bbbb
                &lt;ul&gt;
                    &lt;li&gt;111111&lt;/li&gt;
                    &lt;li&gt;22222&lt;/li&gt;
                    &lt;li&gt;3333&lt;/li&gt;
                &lt;/ul&gt;
            &lt;/li&gt;
            &lt;li&gt;cccc&lt;/li&gt;
        &lt;/ul&gt;
    &lt;/li&gt;
&lt;/ul&gt;
</code></pre>

<p>And I want to search this list via input.
I type text into input and <code>&lt;li&gt;</code> and <code>&lt;ul&gt;</code>'s which are not search result must hide.</p>

<p>Thank you very much and sorry for my bad English</p>
