Example

package main

import (
	"fmt"
	"regexp"
)

func main() {
	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)
	}
}
