}
public static void main(string[] args) throws jdomexception, ioexception {
string xml="<?xml version=\"1.0\" encoding=\"utf-8\" ?><mobaoaccount messagetype=\"usermobilepay\" platformid=\"b2ctest\"><orderno>m20150521084825</orderno><tradeamt>5000.00</tradeamt><commission>0.5</commission><userid>zhuxiaolong</userid><merchid>zhuxiaolong1</merchid><tradetype>0</tradetype><custparam>123</custparam> <notifyurl>http://mobaopay.com/callback.do</notifyurl><tradesummary>订单</tradesummary></mobaoaccount>";
jsonobject json=xml2json(xml.getbytes());
system.out.println(json.tojsonstring());
}
}
执行结果
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"

}
}
