我正在使用Python和Selenium点击网站来选择和预订房间。该网站提供了一个可用的房间表。我想找到一个特定的房间并点击表格中与该房间相关的按钮....但按钮名称会根据房间在桌子中的位置而改变。它所在的位置部分取决于我在网站上运行时可用的其他房间。
在这个例子中，我想保留'Room 34'。
该表似乎由以下标识：
<table id="MainContent_tblPage"....>
包含“房间34”的表格的行或部分由以下标识（根据房间34出现在表格中的位置而变化...这取决于有多少其他房间可用）：
<tr id=MainContent_rptrPropertyList_trContent_1" >
我想在此示例中单击的按钮是：
name="_ctl0:MainContent:rptrPropertyList:_ctl2:rptPropertyRooms:
_ctl0:btnSelect"
（...但按钮名称会根据表格中显示的其他房间而改变...）
我的问题：如果按钮名称根据表内容/行动态变化，如何找到并单击表中的正确按钮...但按钮总是与我想要查找的文本在一行？ / p>
我正在查看的部分的HTML（...抱歉，我不确定如何在不改变可能对回答我的问题很重要的事情的情况下使其更具可读性）：

编辑：我目前正在通过硬编码我点击的按钮来解决这个问题。我使用Selenium导航到创建可用房间表的网页，然后点击今天的相应按钮。但是按钮的名称将来会改变：
room34 = browser.find_element_by_name('_ctl0:MainContent:rptrPropertyList:_ctl31:rptPropertyRooms:_ctl0:btnSelect')
room34.click()
答案 0 :(得分：0)
试试这个xpath - "//div[normalize-space(.)='Room 34']/ancestor::tbody/tr/td//input[@type='submit']"
The Room 34＆＃39;可以用python变量代替。 normalize-space是必需的，因为文本有很多空格。
答案 1 :(得分：0)
点击带有name的按钮作为 _ctl0：MainContent：rptrPropertyList：_ctl2：rptPropertyRooms：_ctl0：btnSelect ，相对于文字为 Room 34 <的元素您可以使用以下任一代码：
使用following：
driver.find_element_by_xpath("//div[@class='room_grid_image']/a[contains(@title,'Room 34')]//following::input[1]").click()
使用following-sibling：
driver.find_element_by_xpath("//div[@class='room_grid_image']/a[contains(@title,'Room 34')]//following-sibling::input[1]").click()
