json-lib中xml轉json的格式區別

今天使用json-lib的xml轉json功能時，有兩種類型數據格式會出現不一樣的結果

1、帶製表符的xml數據格式

    這種格式在嵌套格式數據時，轉換後的數據會將嵌套中一級的去掉，以下面的代碼會httpsql去掉

    下面數據的第一個childrens有兩個子節點，第二個childrens有一個節點

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

    轉換後的結果

[[{"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"}]}]]

 2、壓縮後的xml格式數據格式

    使用壓縮工具將xml數據壓縮成爲一行後，轉換的結果

[[{"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"}}}]]

區別在於childrens的結果，壓縮後轉換會出現httpsql的節點，先記錄，後續再查看源碼
