求正则表达式一个

[criyced]

求正则表达式一个，谢谢各位大虾帮忙。我是想用preg_match_all从一个页面源码里面爬下指定的内容。待摘取的内容如下：
<tr >
<td><div align="center">
<a target='_blank' href='http://vip.stock.finance.sina.com.cn/quotes_service/view/vMS_tradehistory.php?symbol=sh601006&date=2017-08-23'>
2017-08-23 </a>
</div></td>
<td><div align="center">8.950</div></td>
<td><div align="center">8.990</div></td>
<td><div align="center">8.940</div></td>
<td class="tdr"><div align="center">8.880</div></td>
<td class="tdr"><div align="center">24095987</div></td>
<td class="tdr"><div align="center">214915746</div></td>
</tr>
<tr class="tr_2">
<td><div align="center">
<a target='_blank' href='http://vip.stock.finance.sina.com.cn/quotes_service/view/vMS_tradehistory.php?symbol=sh601006&date=2017-08-22'>
2017-08-22 </a>
</div></td>
<td><div align="center">9.010</div></td>
<td><div align="center">9.070</div></td>
<td><div align="center">8.940</div></td>
<td class="tdr"><div align="center">8.910</div></td>
<td class="tdr"><div align="center">43451881</div></td>
<td class="tdr"><div align="center">389421819</div></td>
</tr>
...
谢谢
