Question

我真的很难在这个循环中从div中获取信息。任何人都可以对此有所了解吗？目前我正在使用以下语境：

// li [@ class ='review_tr']

以下内容正常：

//span[@id='hp_hotel_name'] - hotel name
.//p[@class='comments_good'] - positive review
.//p[@class='comments_bad'] - negative review

但我无法抓住任何其他领域，例如：

<div class="name"> - reviewer name
<div class="location"> - reviewer location
<div class="user_type"> - user type.

有谁知道如何抓住这三个领域？

提前感谢您的帮助。

Answer 1

您应该应用与获得正面和负面评论相同的逻辑：

您可以将div中的任何内容与课程name匹配：

.//div[@class='name']

或者更详细地浏览它，以便您不会获得div类name cell_user，例如div ./div[@class='cell_user']/div[@class='user_profile']/div[@class='name']之外的location ：

user_type

获取div和{{1}} {{1}}应该是一项微不足道的任务。
