javascript - 根据模式从字符串中捕获值

Question

Answer 1

诀窍是将模式转换为正则表达式，从给定字符串中捕获预期值:

func capture(pat, str string) []string {
    // Capture all sequences of non-whitespace characters between word boundaries.
    re := strings.Replace(pat, "*", `(\b\S+\b)`, -1)
    groups := regexp.MustCompile(re).FindAllStringSubmatch(str, -1)
    if groups == nil {
        return []string{}
    }
    return groups[0][1:]
}

func main() {
    pat := "The quick brown * jumps over the lazy *"
    str := "The quick brown fox jumps over the lazy dog"

    fmt.Printf("OK: %s\n", capture(pat, str))
    // OK: [fox dog]
}
