XML 转成 数组对象
2012-05-17 07:26:29 来源：WEB开发网核心提示：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，XML 转成 数组对象，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
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
DEMO 以解析struts2配置文件为例
function toJSON()
{
require_once '../classes/XmlToArray.php';
$XML=<<<XML
<?xml version="1.0" encoding="UTF-8"?>

XML;

$xml_to_array = new XmlToArray();
$xml_to_array->setXml($XML);
