el número de teléfono del arrastre Go

Paso 1. En primer lugar obtener la página
   http.Get solicitud de método de una página web
   para determinar si hay un error, si no, mediante la lectura de contenido Web ioutil.ReadAll, devoluciones ReadAll [] bytes, convertida en cadena cuando se lee.
Paso 2. Uso de expresiones regulares iniciar el rastreo número de teléfono
   rePhone = `. 1 [3457689] \ d {. 9}`
   rePhone2 = `(. 1 [3457689] \ D) (\ d {. 4}) (\ d {. 4})`
   \ d representa un número, {9} representa 9 dígitos.
   (1 [3457689] \ d) (\ d {4}) (\ d {4}) de (\ d {4}) representativo de cuatro dígitos en su conjunto, en el medio de 11 dígitos 4 dígitos
   

    re: = regexp.MustCompile (rePhone) analiza las expresiones regulares
    allString: = re.FindAllStringSubmatch (html, -1 ) encontrar todos los partidos, volver [] [] cadena
    de _, V: = Rango allString {
    fmt.Println (V) de recorrido [] [] cadena, la salida es [] cadena
    }
