allow you parse a json file with xpath syntax
Project description
# xjson
xjson 是一个能让你用xpath 语法来解析的json的工具
##Overview
在处理json的时候,如果json 列表有很多元素的话,需要一个个迭代去处理。然而在xpath 却不是这样的,xpath 可以把路径下的都提取出来,这样就能把提取 变成一行,方便写在配置文件中。 xjson 做的就是这么一件事。让你能够以xpath的形式解析json。
{ "success":true, "message":"操作成功!", "result":[ { "firstCategoryList":[ { "name":"工具", "id":"2" } ], "secondCategoryList":[ { "name":"钻削类电动工具", "id":"142", "list":[ { "name":"手电钻", "id":"925" }, { "name":"磁座钻", "id":"928" } ] }, { "name":"磨削类电动工具", "id":"143", "list":[ { "name":"角向磨光机", "id":"936" }, { "name":"磨具电磨", "id":"937" } ] } ] } ] }
如果用json,需要把三级分类提取出来的话,你需要写成
for result in json_content["result"]: for second_category in result["secondCategoryList"]: for third_category in second_category["list"]: print third_category["name"]
不仅混乱,而且需要时刻注意各层嵌套之间的关系,而在 xjson 中,你只需要按照层次关系写成
result/secondCategoryList/list/name
就可以把三级分类全部提取出来了。 而且这样做的话,放在配置文件中,通过配置来提取json是非常方便的。
