获取硒中的特定元素 [英] Getting specific elements in selenium

问题描述

我试图在下图中显示为N06D-X N07X R01A-C01 S01G-X01的元素:

I am trying to get the elements displayed as N06D-X N07X R01A-C01 S01G-X01 in the following image:

现在，我通过这种方式获得了类似WebDriver的东西:

Now, I got something like the WebDriver in this way:

谁= driver.find_element_by_tag_name("span").find_elements_by_tag_name("p")

并获得如下输出:

[<selenium.webdriver.remote.webelement.WebElement (session="1c044455cf883fdedf6845bcd456bfab", element="0.23338884730774767-2")>]

我在Mac Catalina上工作，当我键入:who.text时，由于某种原因它返回一个空列表.我在使用Bs时遇到了类似的麻烦，但是我使用 .string 而不是 .text 解决了它们.在这里 .string 不适用于WebDriver元素.

I am working on Mac Catalina and when I type: who.text it returns an empty list for some reason. I got quite similar troubles with Bs but I solved them with .string rather than .text. Here .string does not work on WebDriver elements.

问题是:我如何用硒获得N06D等物品?

The question is: how can I get the items N06D and so on with selenium?

推荐答案

看来您已经足够亲密了.

Seems you were pretty close enough.

[<selenium.webdriver.remote.webelement.WebElement (session="1c044455cf883fdedf6845bcd456bfab", element="0.23338884730774767-2")>]

代表您正在元素中寻找文本的位置的元素.

represents the element where as you were looking for the text within the element.

要提取文本，例如使用针对 visibility_of_all_elements_located()的WebDriverWait ，您可以使用以下任一

To extract the texts e.g. N06D-X, N07X, etc from all of the <p> tags using Selenium and python you have to induce WebDriverWait for visibility_of_all_elements_located() and you can use either of the following Locator Strategies:

• 使用 CSS_SELECTOR 和 get_attribute("innerHTML"):

print([my_elem.get_attribute("innerHTML") for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "li.data-list__property#who-atc-codes span.data-list__property-value p")))])

使用 XPATH 和 text 属性:

print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//li[@class='data-list__property' and @id='who-atc-codes']//span[@class='data-list__property-value']//p")))])

注意:您必须添加以下导入:

Note : You have to add the following imports :

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

• get_attribute() 方法获取元素的给定属性或属性.
• text 属性返回元素的文本.
• 使用Selenium的文本和innerHTML之间的区别
