str1 := `http://www.suon.co.uk/product/1/7/3/`
re := regexp.MustCompile(`^(?:https?:\/\/)?(?:[^@\/\n]+@)?(?:www\.)?([^:\/\n]+)`)
fmt.Printf("Pattern: %v\n", re.String()) // print pattern
fmt.Println(re.MatchString(str1)) // true
submatchall := re.FindAllString(str1,-1)
for _, element := range submatchall {
fmt.Println(element)
