上一篇記錄了php創建xml文檔的過程，這篇將記錄如何把接受到的xml字符串中的數據和屬性值解析出來，以便進一步對數據進行處理。
xml文件
1. <?xml version="1.0" encoding="utf-8"?>
2. <data>
3. <time value="2011-08-01"/>
4. <time value="2011-08-02"/>
5. <time value="2011-08-03">
6. <worker name="test1" id="14">
7. <hour pid="6" pmid="3"><![CDATA[spot411]]></hour>
8. <hour pid="6" pmid="3"><![CDATA[spot411]]></hour>
9. </worker>
10. </time>
11. <time value="2011-08-04">
12. <worker name="test2" id="6">
13. <hour pid="9" pmid="4"><![CDATA[Pmlal]]></hour>
14. <hour pid="9" pmid="4"><![CDATA[Pmlal]]></hour>
15. <hour pid="9" pmid="4"><![CDATA[Pmlal]]></hour>
16. <hour pid="9" pmid="4"><![CDATA[Pmlal]]></hour>
17. <hour pid="9" pmid="4"><![CDATA[Pmlal]]></hour>
18. <hour pid="9" pmid="4"><![CDATA[Pmlal]]></hour>
19. </worker>
20. </time>
21. <time value="2011-08-05">
22. <worker name="test3" id="1">
23. <hour pid="1" pmid="1"><![CDATA[Teasavant]]></hour>
24. <hour pid="1" pmid="1"><![CDATA[Teasavant]]></hour>
25. <hour pid="1" pmid="1"><![CDATA[Teasavant]]></hour>
26. </worker>
27. <worker name="tony" id="2">
28. <hour pid="1" pmid="1"><![CDATA[Teasavant]]></hour>
29. <hour pid="1" pmid="1"><![CDATA[Teasavant]]></hour>
30. <hour pid="1" pmid="1"><![CDATA[Teasavant]]></hour>
31. <hour pid="1" pmid="1"><![CDATA[Teasavant]]></hour>
32. <hour pid="1" pmid="1"><![CDATA[Teasavant]]></hour>
33. </worker>
34. <worker name="test4" id="4">
35. <hour pid="3" pmid="3"><![CDATA[Red8interactive]]></hour>
36. <hour pid="3" pmid="3"><![CDATA[Red8interactive]]></hour>
37. <hour pid="3" pmid="3"><![CDATA[Red8interactive]]></hour>
38. <hour pid="3" pmid="3"><![CDATA[Red8interactive]]></hour>
39. <hour pid="3" pmid="3"><![CDATA[Red8interactive]]></hour>
40. <hour pid="3" pmid="3"><![CDATA[Red8interactive]]></hour>
41. <hour pid="3" pmid="3"><![CDATA[Red8interactive]]></hour>
42. <hour pid="3" pmid="3"><![CDATA[Red8interactive]]></hour>
43. </worker>
44. </time>
45. <time value="2011-08-06"/>
46. <time value="2011-08-07"/>
47. </data>
1. $xml = new DOMDocument();
2.
3. //$xml->load("timeline.xml");
4. $xmlstring = '<data><time value="2011-08-01"/><time value="2011-08-02"/><time value="2011-08-03"><worker name="test1" id="14"><hour pid="6" pmid="3">spot411</hour><hour pid="6" pmid="3">spot411</hour></worker></time><time value="2011-08-04"><worker name="test2" id="6"><hour pid="9" pmid="4">Pmlal</hour><hour pid="9" pmid="4">Pmlal</hour><hour pid="9" pmid="4">Pmlal</hour><hour pid="9" pmid="4">Pmlal</hour><hour pid="9" pmid="4">Pmlal</hour><hour pid="9" pmid="4">Pmlal</hour></worker></time><time value="2011-08-05"><worker name="test3" id="1"><hour pid="1" pmid="1">Teasavant</hour><hour pid="1" pmid="1">Teasavant</hour><hour pid="1" pmid="1">Teasavant</hour></worker><worker name="test4" id="2"><hour pid="1" pmid="1">Teasavant</hour><hour pid="1" pmid="1">Teasavant</hour><hour pid="1" pmid="1">Teasavant</hour><hour pid="1" pmid="1">Teasavant</hour><hour pid="1" pmid="1">Teasavant</hour></worker><worker name="test5" id="4"><hour pid="3" pmid="3">Red8interactive</hour><hour pid="3" pmid="3">Red8interactive</hour><hour pid="3" pmid="3">Red8interactive</hour><hour pid="3" pmid="3">Red8interactive</hour><hour pid="3" pmid="3">Red8interactive</hour><hour pid="3" pmid="3">Red8interactive</hour><hour pid="3" pmid="3">Red8interactive</hour><hour pid="3" pmid="3">Red8interactive</hour></worker></time><time value="2011-08-06"/><time value="2011-08-07"/></data>';
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."<br>";
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."<br>";
17. //echo $worker_att_id."<br>";
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."<br>";
25. }
26. }
27. }
如果是xml文件，則用
$xml->load("timeline.xml");
如果是解析xml字符串則用
$xml->loadXML($xmlstring);
------------------------------------------------------
獲得節點屬性：getAttribute('id');
獲得節點值：nodeValue;
