Xml转换Map

将xml格式字符串转换成一个map格式，其中key为xml中的节点名称，多层中间用“.”连接，value为节点内容。

 

1.输入

<?xml version="1.0" encoding="UTF-8"?>
<Response>
      <ResultCode>000000</ResultCode>
      <ResultDesc>成功</ResultDesc>
        <nn>
        <test>111</test>
        <a>
            <b>r</b>
        </a>
    </nn>
</Response>

2.输出

Response.nn.test=111
Response.ResultCode=000000
Response.ResultDesc=成功
Response.nn.a.b=r
