    </users>
</root>

读取方式示例

[plain] view plain copy print ?

var?gXml:XML?=?XML(event.result);??
trace(gXml);????????//输出整个XML??
??
var?ns:Namespace?=?new?Namespace("http://xspf.org/ns/0/");??
trace(gXml.ns::users.ns::user.ns::user_name.toString());????//输出带名字空间的XML??
??
trace(gXml.users.user.user_name.toString());?????//输出不带名字空间的XML??

var gXml:XML = XML(event.result);
trace(gXml);        //输出整个XML

var ns:Namespace = new Namespace("http://xspf.org/ns/0/");
trace(gXml.ns::users.ns::user.ns::user_name.toString());    //输出带名字空间的XML

trace(gXml.users.user.user_name.toString());     //输出不带名字空间的XML

Namespaces翻译为名字空间。是为了防止XML中的标签冲突的，如果XML中定义了xmlns，读取的时候就要用“名字空间::子标签”的方式来读取值。
注意：读取标签里的属性里不能使用名字空间。例如读取ns::user标签里的id属性，不能写成ns::user.ns::@id，应该直接写成ns::user.@id。
