C#正则表达式匹配提取网页内容到数组，求指导

<tr>
<tdheight="16"width="120"align="center"><fontface="宋体">100432002000001</font></td>
<tdclass="xl24"height="16"width="55"align="center"><fontface="宋体"><ahref="02boshi/1.htm"target="_blank">周丽丽</a></font></td>
<tdclass="xl24"height="16"width="42"align="center"><fontface="宋体">女</font></td>
<tdclass="xl24"height="16"width="112"align="center"><fontface="宋体">运动人体科学</font></td>
<tdclass="xl24"height="16"width="69"align="center"><fontface="宋体">杨则宜</font></td>
</tr>
<tr>
<tdheight="16"width="120"align="center"><fontface="宋体">100432002000002</font></td>
<tdclass="xl24"height="16"width="55"align="center"><fontface="宋体"><ahref="02boshi/2.htm"target="_blank">洪长青</a></font></td>
<tdclass="xl24"height="16"width="42"align="center"><fontface="宋体">男</font></td>
<tdclass="xl24"height="16"width="112"align="center"><fontface="宋体">运动人体科学</font></td>
<tdclass="xl24"height="16"width="69"align="center"><fontface="宋体">谢敏豪</font></td>
</tr>
想从这段代码中仅仅提取100432002000001和100432002000002并放入数组，请问该怎么写正则表达式？

Answer 1

1.先正向匹配，匹配出
<tdheight="16"width="120"align="center"><fontface="宋体">100432002000001</font></td>

<tdheight="16"width="120"align="center"><fontface="宋体">100432002000002</font></td>
表达式为:
<tdheight="16"width="120"align="center"><fontface="宋体">(.*)?</font></td>

2.匹配出数字
表达式为:
[0-9]{15}

追问

其实直接匹配数字就行了，谢谢！

Answer 2

呵呵，这个很简单，如果你提取的位数是一定的话
string str= "[0-9]{15}"

Answer 3

\d{5,}
