Php SimpleXML在提交后分页

单击submit按钮后，我必须使用php simpleXML构建分页

我的XML文件如下所示：

<events>
    <event_data>
    <club>Club 1</club>
    <categoryid>10</categoryid>
    <category>WellFit®</category>
    <startdate realdate="2013-08-24">1377295200</startdate>
    <enddate realdate="2013-09-07">1378504800</enddate>
    </event_data>

    <event_data>
    <club>Club 2</club>
    <categoryid>9</categoryid>
    <category>Golf</category>
    <startdate realdate="2013-08-24">1377295200</startdate>
    <enddate realdate="2013-09-07">1378504800</enddate>
    </event_data>

    <event_data>
    <club>Club 3</club>
    <categoryid>14</categoryid>
    <category>Tennis</category>
    <startdate realdate="2013-08-24">1377295200</startdate>
    <enddate realdate="2013-09-07">1378504800</enddate>
    </event_data>
