[Golang] golang中使用正则表达式替换字符串

func ReplaceStringByRegex(str, rule, replace string) (string, error) {
    reg, err := regexp.Compile(rule)
    if reg == nil || err != nil {
        return "", errors.New("正则MustCompile错误:" + err.Error())
    }
    return reg.ReplaceAllString(str, replace), nil
}

func TestReplaceStringByRegex(t *testing.T) {
    orgStr := `<p>直接点击<a href="https://www.yidaoerp.cn/user/login" target="_blank">立即注册</a>登陆使用</p>`
    dstStr, err := ReplaceStringByRegex(orgStr, "<[^a>]+>", "")
    log.Println(dstStr, err)
}
