上一篇记录了php创建xml文档的过程，这篇将记录如何把接受到的xml字符串中的数据和属性值解析出来，以便进一步对数据进行处理。

1. $xml = new DOMDocument();
2.
3. //$xml->load("timeline.xml");
4. $xmlstring = '';
5. $xml->loadXML($xmlstring);
6.
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;
