  1. 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

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