remove attribute of html tag
<p>Is it possible to remove the attribute of the first html  tag? So, this:</p>

<pre><code>&lt;div style="display: none; "&gt;aaa&lt;/div&gt;
</code></pre>

<p>becomes </p>

<pre><code>&lt;div&gt;aaa&lt;/div&gt;
</code></pre>

<p>from the following:</p>

<pre><code>&lt;div style="display: none; "&gt;aaa&lt;/div&gt;
&lt;a href="#" style="display: none; "&gt;(bbb)&lt;/a&gt;
&lt;span style="display: none; "&gt;ccc&lt;/span&gt;​
</code></pre>

<p>Many thanks in advance.</p>
