package main
import (
"regexp"
"fmt"
)
func main() {
var re = regexp.MustCompile(`(?m)^\b(?>\.?\w+(?:\[\d+\])?)+$`)
var str = `parent[0].child
parent.child
parent.child1.list[0].child2
parent[500].child
parent0.child
par50ent.child
parent[0].child1[20].child[0]
And some invalid examples are
parent..child
parent[].child
parent[1a].child
parent[a].child
.parent
parent.
I don't know much about regular expressions, so what I came up with is this following line:`
for i, match := range re.FindAllString(str, -1) {
fmt.Println(match, "found at index", i)
}
}
