json-lib中xml转json的格式区别

今天使用json-lib的xml转json功能时，有两种类型数据格式会出现不同的结果

一、带制表符的xml数据格式

    这种格式在嵌套格式数据时，转换后的数据会将嵌套中一级的去掉，如下面的代码会httpsql去掉

    下面数据的第一个childrens有两个子节点，第二个childrens有一个节点

<?xml version="1.0" encoding="UTF-8"?>

    转换后的结果

[[{"url":[],"starttime":"2","useragent":"3","httpreqnum":"4","timenum":"5","concurrencynum":"6","jdbcexenum":"7","jdbcerrornum":"8","jdbctime":"9","commitnum":"10","rollbacknum":"11","readnum":"12","updatenum":"13","ipaddr":"14","loginname":"15","loginusername":"16","childrens":[{"sql":"1","exesqltime":"2"},{"sql":"3","exesqltime":"4"}]},{"url":"1","starttime":"2","useragent":"3","httpreqnum":"4","timenum":"5","concurrencynum":"6","jdbcexenum":"7","jdbcerrornum":"8","jdbctime":"9","commitnum":"10","rollbacknum":"11","readnum":"12","updatenum":"13","ipaddr":"14","loginname":"15","loginusername":"16","childrens":[{"sql":"3","exesqltime":"4"}]}]]

 二、压缩后的xml格式数据格式

    使用压缩工具将xml数据压缩成为一行后，转换的结果

[[{"url":[],"starttime":"2","useragent":"3","httpreqnum":"4","timenum":"5","concurrencynum":"6","jdbcexenum":"7","jdbcerrornum":"8","jdbctime":"9","commitnum":"10","rollbacknum":"11","readnum":"12","updatenum":"13","ipaddr":"14","loginname":"15","loginusername":"16","childrens":[{"sql":"1","exesqltime":"2"},{"sql":"3","exesqltime":"4"}]},{"url":"1","starttime":"2","useragent":"3","httpreqnum":"4","timenum":"5","concurrencynum":"6","jdbcexenum":"7","jdbcerrornum":"8","jdbctime":"9","commitnum":"10","rollbacknum":"11","readnum":"12","updatenum":"13","ipaddr":"14","loginname":"15","loginusername":"16","childrens":{"httpsql":{"sql":"3","exesqltime":"4"}}}]]

区别在于childrens的结果，压缩后转换会出现httpsql的节点，先记录，后续再查看源码
