how to use php to replace certain content within a table tag
<p>I have thousands of html pages which contains below table content ~</p>

<pre><code>&lt;table height="94" cellpadding="0" width="760" border="0" cellspacing="0"&gt;
..... 
&lt;/table&gt;
</code></pre>

<p>I want to delete this table tag:~</p>

<pre><code>&lt;table height="94" cellpadding="0" width="760" border="0" cellspacing="0"&gt;
</code></pre>

<p>and the content within it.</p>

<p>I tried:~</p>

<pre><code>preg_replace("/&lt;(\/?table height="/94/".*?)&gt;/si","",$str);
</code></pre>

<p>but failed，it just removed all of my  tags and their content.</p>

<p>thanks in advance</p>
