jsonqueryvsmxj
jsonquery is a Go library that allows you to parse and extract data from JSON documents using JSONPath expressions. JSONPath is similar to XPath, but it is designed specifically for working with JSON documents.
The jsonquery library allows you to traverse the JSON tree structure and
extract values using JSONPath expressions. It provides a simple and intuitive API
for querying the JSON data, and it is built on top of the popular jsoniter library.
mxj is a Go library for working with JSON and XML data. It allows you to convert between JSON and XML, merge JSON and XML documents, and extract values from JSON and XML using a simple and intuitive API.
One of the main features of mxj is its ability to work with JSON and XML data in a struct-like manner, allowing you to access values using dot notation.
Example Use
package main
import (
"fmt"
"log"
"github.com/antchfx/jsonquery"
)
func main() {
// Parse the JSON string
doc, err := jsonquery.Parse([]byte(`
{
"name": "John Doe",
"age": 30,
"address": {
"street": "Main St",
"city": "Anytown",
"state": "CA",
"zip": "12345"
},
"phones": [
"555-555-5555",
"555-555-5556"
]
}
`))
if err != nil {
log.Fatal(err)
}
// Extract the name
name := jsonquery.FindOne(doc, "name")
fmt.Println(name.InnerText()) // "John Doe"
// Extract the city
city := jsonquery.FindOne(doc, "address.city")
fmt.Println(city.InnerText()) // "Anytown"
// Extract all phone numbers
phones := jsonquery.Find(doc, "phones[*]")
for _, phone := range phones {
fmt.Println(phone.InnerText())
}
// "555-555-5555"
// "555-555-5556"
}
