Converting a string to array

I am working with Go for writing a terratest and I have string "[[IFN_EYE_HUBW_DEV_AUTO_01] [IFN_EW_HUBW_DEV_AUTO_02]]". How can I split this to an array to get "IFN_EYE_HUBW_DEV_AUTO_01" and "IFN_EW_HUBW_DEV_AUTO_02" as 1st and 2nd element of the array in go?

You can simply replace all [ and ] and then split them with Fields as:

package main

import (
    "fmt"
    "strings"
)

func main() {
    inp := "[[IFN_EYE_HUBW_DEV_AUTO_01] [IFN_EW_HUBW_DEV_AUTO_02]]"
    inp = strings.ReplaceAll(inp, "[", "")
    inp = strings.ReplaceAll(inp, "]", "")
    out := strings.Fields(inp)
    fmt.Printf("%v, %v", out[0], out[1])
}

Ideally, you should use regex for pattern matching but the above will work just fine for this task.

Note: It will replace all the [ and ] brackets so if a string has these brackets then will be replaced too.
