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

function toJSON()
{
require_once '../classes/XmlToArray.php';
$XML=
li> "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
add.action
/emp/add_suc.jsp
/emp/list.jsp
delete.action
/emp/delete_suc.jsp
update.action
/emp/edit_suc.jsp
/emp/edit.jsp
XML;
header("Content-type: text/html; charset=utf-8") ;
$xml_to_array = new XmlToArray();
$xml_to_array->setXml($XML);
// 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
//$xml_to_array->setAttributeAsName("attributeAsName")->setContentAsName("contentasName");
$r = $xml_to_array->parseXml(true);
print_r( $r ) ;
}
// 打印结果：
{"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"}}]}}}
