## 运行结果 ##

*  XML原文：

<?xml version="1.0" encoding="utf-8" ?>
    <MoBaoAccount MessageType="UserMobilePay" PlatformID="b2ctest">
        <OrderNo>M20150521084825</OrderNo>
        <TradeAmt>5000.00</TradeAmt>
        <Commission>0.5</Commission>
        <UserID>xiaolong</UserID>
        <MerchID>xiaolong1</MerchID>
        <tradeType>0</tradeType>
        <CustParam>123</CustParam>
        <NotifyUrl>http://mobaopay.com/callback.do</NotifyUrl>
        <TradeSummary>订单</TradeSummary>
    </MoBaoAccount>

*  转换后的json格式数据

{
        "MoBaoAccount": { "Commission": [ "0.5" ], "CustParam": [ "123" ], "MerchID": [ "zhuxiaolong1" ], "NotifyUrl": [ "http://mobaopay.com/callback.do" ], "OrderNo": [ "M20150521084825" ], "TradeAmt": [ "5000.00" ], "TradeSummary": [ "订单" ], "UserID": [ "zhuxiaolong" ], "tradeType": [ "0" ] } }
