正则去除一些DIV内的内容。
我想正则去除一些DIV的内容。div id 或者class 带comment或者share的（comment和share是一个模糊匹配。），比如
$htmls = <<<EOT<br />
<div id="content"><br />
Main content.<br />
</div><br />
<div id="comment"><br />
<ul><br />
<li class="comment"><br />
<div class="header-comment"><br />
Comment:<br />
<span class="date-comment">8/11/2012, 21:25</span><br />
</div><br />
<h4>Some Text</h4><br />
<p class="test-comment">Blah~~ Blah~~ Blah~~</p><br />
<div class="share"><br />
<div class="vote"><br />
<a class="vota yes" title="Like">2</a><br />
<a class="vota no" title="Unlike">0</a><br />
</div><br />
</div><br />
</li><br />
<li class="comment"><br />
<div class="header-comment"><br />
Comment:<br />
<span class="date-comment">8/11/2012, 23:08</span><br />
</div><br />
<h4>Other Text</h4><br />
<p class="test-comment">Blah~~ Blah~~ Blah~~</p><br />
<div class="share"><br />
<div class="vote"><br />
<a class="vota yes" title="Like">4</a><br />
<a class="vota no" title="Unlike">0</a><br />
</div><br />
</div><br />
</li> <br />
</ul><br />
</div><br />
EOT;<br />
<br />
$htmls = preg_replace('/<div[^>]*(comment|share)[^>]*>(.*?)<\/div>/is', '', $htmls);<br />
echo $htmls;</div><br />
<div id="footer"><br />
Footer content.<br />
</div><br />
EOT;
