不点击所有标签，不循环一次问题

Question

我正在尝试按一下网页上的标签，如下所示。不幸的是，尽管inspectchrome中正确的xpath，它似乎只点击了一些选项卡。我只能假设它没有点击所有的标签，因为没有使用完整的xpath。

但是。。 我尝试更改xpath:

//div[@class="KambiBC-collapsible-container KambiBC-mod-event-group-container"] 收件人：

//div[@class='KambiBC-event-groups-list']//div[@class="KambiBC-collapsible-container KambiBC-mod-event-group-container"] 用于：

clickMe = wait(driver, 10).until(EC.element_to_be_clickable((By.XPATH,'(//div[@class="KambiBC-collapsible-container KambiBC-mod-event-group-container"])[%s]' % str(index + 1))))    

但问题依然存在。 我也尝试过使用CSS：

^{pr2}$

但是这总是给我错误… 用于：

clickMe = wait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR,'("#KambiBC-contentWrapper__bottom > div > div > div > div > div.KambiBC-quick-browse-container.KambiBC-quick-browse-container--list-only-mode > div.KambiBC-quick-browse__list.KambiBC-delay-scroll > div > div.KambiBC-time-ordered-list-container > div.KambiBC-time-ordered-list-content > div > div > div > header")[%s]' % str(index + 1))))

需要注意的是，我想点击所有未打开的选项卡，我似乎不能使用CSS选择器来找到足够具体的元素，因为我认为在这种情况下，它不允许您缩小class元素的范围。在

有没有办法绕过这个问题，不点击所有的东西？在

需要注意的是，我正在使用。。。在

对于索引中的索引：

indexes = [index for index in range(len(options))]
shuffle(indexes)
for index in indexes:

有没有更优雅的方式来使用for 1循环？在

[import sys
sys.exit()][1]

这将循环从每个联盟1到1的所有比赛，收集所有需要的相关数据。通过在每个查询前面加上.并通过match.find_element_by_xpath('.//your-query-here')选择一个匹配项，可以在每个匹配中收集进一步的数据。让我知道这是否奏效！在

Answer 2

OP's code without extra imports

发生此错误是因为site对操作所需的制表符的XPath不连续。它有一个缺口。例如，现在我找不到

//*[@id=“KambiBC-contentWrapper_ubottom”]/div/div/div/div[3]/div1/div/div[3]/div[2]/div/div[2]/header

前一段时间在游戏开始前，我找不到

//*[@id=“KambiBC-contentWrapper_ubottom”]/div/div/div/div[3]/div1/div/div[3]/div[2]/div/div[1]/header

当我谈到index时，我指的是上面粗体部分。

当游戏上线时，标签会突然将索引从2变为1。（粗体部分更改）在这两种情况下，都存在间隙：要么找不到1，要么找不到2。在

我想，产生这种差距的原因是，两者之间还有一个元素是不可点击的。见下图。

这个league是造成这种差距的原因。因此，每当代码命中league所占的索引时，它就会超时。因为League按钮和其他选项卡会切换League的位置，所以当位置发生变化时，索引会交换。（我想这就是为什么我首先找不到粗体部分为1的Xpath，后来又找不到粗体部分为2的原因。）

下面是OP的一部分代码，你可以在末尾看到str（index+1）。在

indexes = [index for index in range(len(options))] # 
shuffle(indexes) # the OP use shuffle from random. Still 0 and 1 is contained.
path = '(//div[@class="KambiBC-collapsible-container KambiBC-mod-event-group-container"])'
for index in indexes:
    # Because there are some indexes are missing because of League button,
    # nothing can be found at the index and it times out.
    clickMe = wait(driver, 10).until(
EC.element_to_be_clickable((By.XPATH, path + '[%s]' % str(index + 1))))

解决方案

尝试捕获超时异常以跳过League所占用的索引。您还可以保留一个计数器，以便在一个页面上只捕获一个超时异常。如果有第二次超时，您知道除了League按钮之外还有其他问题，应该停止。在
