遍历JSON键和值，并同时替换golang中的指定匹配值

Question

Is there any way to loop all over keys and values of json and thereby confirming and replacing a specific value by matched path or matched compared key or value and simultaneously creating a new interface of out of the json after being confirmed with the key new value in Golang.

This an example i saw that loops through all values https://play.golang.org/p/xtiT2iGocBg but i have no idea of replacing values by matched path or value

Finally! I completed the full specification of what i were looking for!!

   package main

            "value1":10,
