<div class="detail-journey-head">
                        <i class="icon detail-journey-day">D1</i>
                        <strong>第1天</strong>

                            <strong>北京</strong>

                                    <i class="icon detail-journey-transport-train"></i>

                                <strong>南京</strong>

                    </div>

不管是css还是xpath，都没法精确取出 “南京”

.detail-journey-head > strong:nth-child(3)

怎么会哈，用xpath即可，写法如下： //div[contains(@class,'detail-journey-head')]/strong[3]

//div[@class='detail-journey-head']/strong[last()] 还可以这样写，给自己点赞~☺ 参考：
