如何使用selenium和python创建具有相同xpath的元素列表? [英] How can I create a list of elements with the same xpath using selenium with python?

问题描述

我需要单击同一网页上同一表中的几个元素.我当时想使用for循环来执行此操作，但是为了执行该操作，我首先需要创建这些元素的列表.

I need to click on several elements from the same table on the same webpage. I was thinking to do so with a for loop but in order to perform that action I first need to create a list of these elements.

//table[@border='1']//a

这是从表中选择所有元素的xpath，如何创建所有这些元素的列表?

This is the xpath which selects all the elements from the table, how can I create a list of all these?

推荐答案

@SergiyKonoplyaniy答案是正确的方向，一个接一个地解决您的查询:

While @SergiyKonoplyaniy answer was in the right direction, addressing your queries one by one:

• 如何创建具有相同xpath的元素列表:要创建元素列表，您需要使用

• How can I create a list of elements with the same xpath : To create a list of elements you need to use find_elements_by_xpath(xpath) which will create a List of elements matching the xpath you have specified.

示例:

my_links = driver.find_elements_by_xpath("//table[@border='1']//a")

需要单击多个元素:由于您需要click()在多个元素上，因此必须遍历在 List 如下:

Need to click on several elements: As you need to click() on several elements you have to iterate through all the elements you have captured in the List as follows:

for link in my_links:
    link.click()

现在最重要的方面是，根据您的 xpath //table[@border='1']//a每个元素:

Now the most important aspect is, as per your xpath //table[@border='1']//a each and every element:

• 具有3个不同的阶段，分别是存在，可见性和交互性(即可点击性)

• 要收集 List 中的元素，您应始终调用具有 expected-conditions 的服务员，如

• Has 3 distinct stages interms of presence, visibility and interactibility (i.e. clickability)

• To collect the elements in a List you should always invoke a waiter with expected-conditions as visibility_of_all_elements_located(locator) as follows:

my_list = WebDriverWait(driver, 20).until(expected_conditions.visibility_of_all_elements_located((By.XPATH, "//table[@border='1']//a")))

作为您问题的解决方案的伪代码将是:

The pseudo code as a solution for your question will be:

my_links = WebDriverWait(driver, 20).until(expected_conditions.visibility_of_all_elements_located((By.XPATH, "//table[@border='1']//a")))
for link in my_links:
    link.click()

供以后参考，如果您打算在任何特定元素上调用click()，请始终以 =期望条件作为

For your future reference, if you intend to invoke click() on any particular element always invoke a waiter with expected-conditions as element_to_be_clickable(locator) as follows:

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "desired_element_xpath"))).click()
