JsonPath Enhance

A golang implementation of JsonPath syntax. follow the majority rules in http://goessner.net/articles/JsonPath/ but also with some minor differences.

Golang Version Required: 1.5+

说明：该项目fork了https://github.com/oliveagle/jsonpath， 并在上面做了功能扩展，主要包括：

1. 增加了字符串分割成数组的能力，s_split()
2. 增加了二维数组的遍历的能力，2d_slice_range()
3. 支持了将Json中的Json字符串转Json的能力，弥补JsonPath无法对嵌套的Json字符串下钻处理的问题，s_convert_to_json()

Get Started

go get github.com/yaoyinfeng/json_path_enhance

example code:

import (
    jsonpath "github.com/yaoyinfeng/json_path_enhance"
    "encoding/json"
)

var json_data interface{}
json.Unmarshal([]byte(data), &json_data)

pat, _ := jsonpath.Compile(`$.book[:].title.s_split(:)`)
res, err := pat.Lookup(json_data)
