7.            $timedom = $xml->getElementsByTagName("time");

8.            $d_array = array();

9.            foreach ($timedom as $times){

10.               $time_att_value = $times->getAttribute("value");

11.               echo $time_att_value."
";

12.               $d_worker = $times->getElementsByTagName("worker");

13.               foreach ($d_worker as $d_work){

14.                   $worker_att_id = $d_work->getAttribute("id");

15.                   $worker_att_name = $d_work->getAttribute("name");

16.                   echo $worker_att_name."
";

17.                   //echo $worker_att_id."
";

18.                   $d_hours = $d_work->getElementsByTagName("hour");

19.                   foreach ($d_hours as $d_hour){

20.                       $hour_att_pid = $d_hour->getAttribute("pid");

21.                       $hour_att_pmid = $d_hour->getAttribute("pmid");

22.                      

23.                       echo count($d_hour);

24.                       echo $d_hour->nodeValue."
";

25.                   }

26.               }

27.           }

如果是xml文件,则用

$xml->load("timeline.xml");

如果是解析xml字符串则用

$xml->loadXML($xmlstring);

获得节点属性:getAttribute('id');

获得节点值:nodeValue;
