get parent li text by jquery
<p>I need alert <strong>thisparenttext</strong> in following code by clicking on <strong>clickedlicontent</strong></p>

<pre><code>&lt;script&gt;
 $("#one").live("click",function(){
 var partxt=$(this).parent().parent().text();
 alert(partxt);
 });
&lt;/script&gt;
&lt;ul&gt;
    &lt;li&gt;thisparenttext&lt;ul&gt;&lt;li id="one"&gt;clickedlicontent&lt;/li&gt;&lt;/ul&gt;&lt;/li&gt;
    &lt;li&gt;bb&lt;/li&gt;
&lt;/ul&gt;
</code></pre>

<p>In other word, I want take only the text of first parent of clicked li, not all its all html codes. </p>
