Question

在Quora用户个人资料页面上，我想通过单击“更多”来显示每个用户答案的全文，但我无法获得“更多”元素列表，而是得到了一个空列表，怎么办？

这是我的代码：

float

以下是用户个人资料的示例： https://www.quora.com/profile/Ashley-Isabella-3

Answer 1

那是因为您使用了错误的CSS选择器。尝试：

more_buttons = browser.find_elements_by_class_name('ui_qtext_more_link')

通过在常规浏览器中右键单击元素并单击“检查”，可以找到正确的属性。

Answer 2

实际上，您位于以下链接之后（单击时），因此您可以仅收集链接，然后对.get使用循环。使用return [...document.querySelectorAll ]语法

from selenium import webdriver

d = webdriver.Chrome()
d.get("https://www.quora.com/profile/Ashley-Isabella-3")
links = d.execute_script("return [...document.querySelectorAll('.ui_qtext_more_link')].map(link => link['href'])")
info = []
for link in links:
    d.get(link)
    pageInfo = d.execute_script("return [...document.querySelectorAll('.ui_qtext_para')].map(link => link.innerText)")
    info.append(pageInfo)
print(info)

Answer 3

在Quora用户个人资料页面上，单击文本为（更多）的链接并检索用户答案，您可以使用以下解决方案：

代码块：

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

driver=webdriver.Firefox(executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
driver.get("https://www.quora.com/profile/Ashley-Isabella-3")
more_buttons = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "a.ui_qtext_more_link")))
for more_button in more_buttons:
    more_button.click()
my_text_elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div.ui_qtext_expanded>span.ui_qtext_rendered_qtext>p>b")))
for my_text_element in my_text_elements:
    print(my_text_element.text)
