XML转成数组对象

时间：2021-07-01 10:21:17 帮助过：8人阅读

将XML内容解析后返回一个对应的数组对象，并且可以通过参数设置来设置返回类型【数组、JSON】 默认:数组
由于是基于simplexml_load_string 对带有命名空间的XML解析不是很好，会丢失命名空间内容 以上是在测试中得到的结论，后续版本会解决这个问题。
这个可以满足一般的使用需求
  1. function toJSON()
  2. {
  3. require_once '../classes/XmlToArray.php';
  4. $XML=<<
  5. "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

  20. delete.action
  21. /emp/delete_suc.jsp
  24. update.action

  28. /emp/edit.jsp
  34. XML;
  36. header("Content-type: text/html; charset=utf-8") ;
  37. $xml_to_array = new XmlToArray();
  38. $xml_to_array->setXml($XML);
  39. // 当标签名与内置属性有冲突的时候可以自定义相关属性名,一般其概况不需要设置
  40. //$xml_to_array->setAttributeAsName("attributeAsName")->setContentAsName("contentasName");
  41. $r = $xml_to_array->parseXml(true);
  42. print_r( $r ) ;
  43. }
  44. // 打印结果：
  46. {"struts":{"attributes":[],"content":"","constant":{"attributes":{"name":"struts.objectFactory","value":"spring"},"content":""},"package":{"attributes":{"name":"crm_employee","extends":"struts-default","namespace":"\/emp"},"content":"","action":[{"attributes":{"name":"add","class":"addBean","method":"add"},"content":"","result":[{"attributes":[],"content":"add.action"},{"attributes":[],"content":"\/emp\/add_suc.jsp"}]},{"attributes":{"name":"list","class":"listBean","method":"list"},"content":"","result":{"attributes":[],"content":"\/emp\/list.jsp"}},{"attributes":{"name":"delete","class":"deleteBean","method":"delete"},"content":"","result":{"attributes":[],"content":"\/emp\/delete_suc.jsp"}},{"attributes":{"name":"update","class":"updateBean","method":"update"},"content":"","result":{"attributes":[],"content":"\/emp\/edit_suc.jsp"}},{"attributes":{"name":"edit","class":"editBean","method":"edit"},"content":"","result":{"attributes":[],"content":"\/emp\/edit.jsp"}}]}}}
