php DOMDocument应用实例(XML创建、添加、删除、修改)

2. $xmlpatch = 'index.xml';
3. $_id = '1';
4. $_title = 'title1';
5. $_content = 'content1';
6. $_author = 'author1';
7. $_sendtime = 'time1';
8. $_htmlpatch = '1.html';
9. $doc = new DOMDocument('1.0', 'utf-8');
10. $doc -> formatOutput = true;
11. $root = $doc -> createElement_x('root');//新建节点
12. $index = $doc -> createElement_x('index');//新建节点
13. $url = $doc -> createAttribute('url');//新建属性
14. $patch = $doc -> createTextNode($_htmlpatch);//新建TEXT值
15. $url -> appendChild($patch);//将$patch文本设为$url属性的值
16. $id = $doc -> createAttribute('id');
17. $newsid = $doc -> createTextNode($_id);
18. $id -> appendChild($newsid);
19. $title = $doc -> createAttribute('title');
20. $newstitle = $doc -> createTextNode($_title);
21. $title -> appendChild($newstitle);
22. $content = $doc -> createTextNode($_content);//节点值
23. $author = $doc -> createAttribute('author');
24. $newsauthor = $doc -> createTextNode($_author);
25. $author -> appendChild($newsauthor);
26. $sendtime = $doc -> createAttribute('time');
27. $newssendtime = $doc -> createTextNode($_sendtime);
28. $sendtime -> appendChild($newssendtime);
29. $index -> appendChild($id);//将$id设为index节点的属性，以下类同
30. $index -> appendChild($title);
31. $index -> appendChild($content);
32. $index -> appendChild($url);
33. $index -> appendChild($author);
34. $index -> appendChild($sendtime);
35. $root -> appendChild($index);//设置index为root字节点
36. $doc -> appendChild($root);//设置root为跟节点
37. $doc -> save($xmlpatch);//保存文件
38. echo $xmlpatch . ' has create success';
39. ?>

3. 2、add.php 增加功能(跟index.php文件差不多，主要就是加个load载入跟 $root = $doc -> documentElement获得跟节点

4. $xmlpatch = 'index.xml';
5. $_id = '2';
6. $_title = 'title2';
7. $_content = 'content2';
8. $_author = 'author2';
9. $_sendtime = 'time2';
10. $_htmlpatch = '2.html';
11. $doc = new DOMDocument();
12. $doc -> formatOutput = true;
13. if($doc -> load($xmlpatch)) {
14. $root = $doc -> documentElement;//获得根节点(root)
15. $index = $doc -> createElement_x('index');
16. $url = $doc -> createAttribute('url');
17. $patch = $doc -> createTextNode($_htmlpatch);
18. $url -> appendChild($patch);
19. $id = $doc -> createAttribute('id');
20. $newsid = $doc -> createTextNode($_id);
21. $id -> appendChild($newsid);
22. $title = $doc -> createAttribute('title');
23. $newstitle = $doc -> createTextNode($_title);
24. $title -> appendChild($newstitle);
25. $content = $doc -> createTextNode($_content);
26. $author = $doc -> createAttribute('author');
27. $newsauthor = $doc -> createTextNode($_author);
28. $author -> appendChild($newsauthor);
29. $sendtime = $doc -> createAttribute('time');
30. $newssendtime = $doc -> createTextNode($_sendtime);
31. $sendtime -> appendChild($newssendtime);
32. $index -> appendChild($id);
33. $index -> appendChild($title);
34. $index -> appendChild($content);
35. $index -> appendChild($url);
36. $index -> appendChild($author);
37. $index -> appendChild($sendtime);
38. $root -> appendChild($index);
39. $doc -> save($xmlpatch);
40. echo $_id . ' has been added in ' . $xmlpatch;
41. } else {
42. echo 'xml file loaded error!';
43. }
44. ?>
