关于采集分页的问题

请教内容页分页地址区域代码如何找,试了好多次都不行,

如下代码:
<style>
#cms4_zutu_nav1 {
    margin:5px 0;
    text-align:center;
}
#cms4_zutu_nav1 a {
    display:-moz-inline-box; /* Moz FF */
    padding:2px 5px;
    margin:2px 1px;
    line-height:24px;
    font-size:12px;
    color:#686868;
    text-decoration:none;
    cursor:pointer;   
    border:1px solid #ccc;
    background: url();
}
#cms4_zutu_nav1 a:hover {
    color:red;
}
</style>
<div id="cms4_zutu_nav1">
    <a href="http://learning.sohu.com/20080609/n257374946.shtml" title="上一页">上一页</a>
            <a href="http://learning.sohu.com/20080609/n257374946.shtml" title="1">1</a>
                <a href="#" title="2" style="color:red">2</a>
                <a href="http://learning.sohu.com/20080609/n257374946_2.shtml" title="3">3</a>
        <a href="http://learning.sohu.com/20080609/n257374946_2.shtml" title="下一页">下一页</a>
</div>
