How to find two same text nodes
<p>I have a table with data in in. For simplicity lets say it has only one column and no header. I want JQuery to iterate over all rows to see if the text in any of the cells in the same column is repeated in another row. Is there a simple way to do this?</p>

<pre><code>&lt;tr&gt;&lt;td&gt;one&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;two&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;three&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;four&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;five&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;one&lt;/td&gt;&lt;/tr&gt;   &lt;!--It is doubled--&gt;
&lt;tr&gt;&lt;td&gt;six&lt;/td&gt;&lt;/tr&gt;
</code></pre>
