xml+php动态载入与分页
<p>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<a href="http://www.phpchina.com/javascript:;" onClick="javascript:tagshow(event, 'xml');" target="_self"><u><strong>xml</strong></u></a>文件．然后在把数据绑定到<a href="http://www.phpchina.com/javascript:;" onClick="javascript:tagshow(event, 'html');" target="_self"><u><strong>html</strong></u></a>上的．我就用php也做了一个以下是源文件． <br><br>-----------------xml.htm------------------ <br><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <br><html> <br><head> <br><meta http-equiv="Content-Type" content="text/html;
