Extjs 解析后台xml数据

Question

我想用ExtJS解析后台传回的xml数据，但是后台的xml数据是经过soap协议封装的，请问有没有简便的方法去解析？

Answer 1

getelementsbytagname，getattriute，nodevalue这些来遍历提取xml的值，js如何操作xml自己看看

Answer 2

能是用xml作为grid的数据源还是什么？
规则的xml数据结构可以用XMLStore设置一些属性就行了
如果不是规则的xml结构就得自己解析了

Answer 3

是不规则的，我是调用服务器web service获取数据，web service传回的xml像这样
