XML 转成 数组对象

程序员文章站 2024-01-13 11:17:40

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=

  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：
