php正则表达式抓取网页部分内容

各位大哥谁能帮忙弄个正则表达式
html代码：
<tr>
<td class="rank">1</td>
<td><a target="_blank" href="A1">A1</a></td>
<td>98678</td>
<td>101516</td>
<td>710610</td>
<td>
<a target="_blank" href="A2">A2</a>
<a target="_blank" href="A3">A3</a>
<a target="_blank" href="A4">A4</a>
</td>
</tr>
<tr>
<td class="rank">2</td>
<td><a target="_blank" href="B1">B1</a></td>
<td>24692</td>
<td>33096</td>
<td>231669</td>>
<td>
<a target="_blank" href="B2">B2</a>
<a target="_blank" href="B3">B3</a>
<a target="_blank" href="B4">B4</a>
</td>
</tr>

我想读取的到数据是

<td><a target="_blank" href="A1">A1</a></td>
<td><a target="_blank" href="B1">B1</a></td>

这部分请问这个正则如何写
万分感激啊
