PHP通過DOM解析XML檔案或者xml字串_PHP教程

上一篇記錄了php建立xml文檔的過程，這篇將記錄如何把接受到的xml字串中的資料和屬性值解析出來，以便進一步對資料進行處理。

1. $xml = new DOMDocument();

2.

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

4. $xmlstring = 'spot411spot411PmlalPmlalPmlalPmlalPmlalPmlalTeasavantTeasavantTeasavantTeasavantTeasavantTeasavantTeasavantTeasavantRed8interactiveRed8interactiveRed8interactiveRed8interactiveRed8interactiveRed8interactiveRed8interactiveRed8interactive';

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檔案，則用

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

如果是解析xml字串則用

$xml->loadXML($xmlstring);

------------------------------------------------------

獲得節點屬性：getAttribute('id');

獲得節點值：nodeValue;
