I am using jsonpath in golang but I can't get all the objects of the following json that contain in type iPhone:
{ "firstName": "John", "lastName": "doe", "age": 26, "address": { "streetAddress": "naist street", "city": "Nara", "postalCode": "630-0192" }, "phoneNumbers": [ { "type": "iPhone", "number": "0123-4567-8888" }, { "type": "home", "number": "0123-4567-8910" }, { "type": "iPhone", "number": "0123-4567-8910" } ]} I am working with golang and I know that the following jsonpath works:
$.phoneNumbers[?(@.type == "iPhone")] The problem I have is that it is a service in which I have input a json path like the following:
$.[*].phoneNumbers[*].type And the value that I have to look for, I am doing it in the following way:
values, err := jsonpath.Get(jsonPath, data) for _, value := range values { if err != nil { continue } if value.(string) == "iPhone" { } } At this point I cant get the output like:
[{ "type": "iPhone", "number": "0123-4567-8888" }, { "type": "iPhone", "number": "0123-4567-8888" }] I cant use the [?(@.)] format it is necessary to make with if. Any idea? Thanks

I cooked up an example using Peter Ohler's ojg package. Here's what the implementation looks like:
package main import ( "fmt" "" "" ) var jsonString string = `{ // Your JSON string }` func main() { obj, err := oj.ParseString(jsonString) if err != nil { panic(err) } x, err := jp.ParseString(`$.phoneNumbers[?(@.type == "iPhone")]`) if err != nil { panic(err) } ys := x.Get(obj) for k, v := range ys { fmt.Println(k, "=>", v) } } // Output: // 0 => map[number:0123-4567-8888 type:iPhone] // 1 => map[number:0123-4567-8910 type:iPhone]
