xml+php动态载入与分页

这是在看太平洋网的评论时看到的，太平洋网是用jsp做为后台语言，用来产生xml文件．然后在把数据绑定到html上的．我就用php也做了一个以下是源文件．

-----------------xml.htm------------------

店铺列表
商铺名称	经营者	店铺级别	店铺简介
名称	经营人	级别	简介

-----------------xml.php------------------

$Vars[$key] = $val;
}
while(list($key2, $val2) = each($post_vars)) {
$Vars[$key2] = $val2;

以上的php，注释的是我连接数据库取得的数据，既然放上来测试，也没有数据库连接，所以改了一下．偶也是刚接解xml不久，很多地方还是不很懂．见笑了......
