C# code

<div class="pagebox"><span class="pagebox_pre_nolink">上一页</span><span class="pagebox_num_nonce">1</span><span class="pagebox_num"><a target="_self" href="102641554-2.html" class="page">2</a></span><span class="pagebox_num"><a target="_self" href="102641554-3.html" class="page">3</a></span><span class="pagebox_num"><a target="_self" href="102641554-4.html" class="page">4</a></span><span class="pagebox_num"><a target="_self" href="102641554-5.html" class="page">5</a></span><span class="pagebox_next"><a href="102641554-2.html">下一页</a></span></div>

输出 102641554-2.html 2
  102641554-3.html 3
  102641554-4.html 4
  102641554-5.html 5

也是说要 class="page"的标签的src属性和值 ，两个都要 ，源数据还有其它的标签 所以class="page"条件也要 。

[解决办法]
href="([^"]+)"[^>]*>(\d+)</a>
