如何使用Selenium抓取多个URL的内容？Python

Question

driver = webdriver.Chrome(r'XXXX\chromedriver.exe')
FB_bloomberg_URL="https://www.bloomberg.com/quote/FB:US"
driver.get(FB_bloomberg_URL)

eList = driver.find_elements_by_class_name('link__f5415c25')
hrefList = []
for e in eList:
    hrefList.append(e.get_attribute('href'))

for href in hrefList:
    print(href)

我有上面的编码来提取使用硒 - 蟒蛇的href链接。我想提取每个人的个人资料“董事会成员”中的内容。我知道如何逐个提取它们，但不知道如何编写循环来执行此操作。

以下是我的代码:

driver2 = webdriver.Chrome(r'XXXX\chromedriver.exe')
driver2.get("https://www.bloomberg.com/profiles/people/15103277-mark-elliot-zuckerberg")

boardmembership_table=driver2.find_elements_by_xpath('//*[@id="root"]/div/section/div[5]')[0]
boardmembership_table.text

任何想法都很感谢！

Answer 1

这是应该有效的方法。

driver = webdriver.Chrome(r'XXXX\chromedriver.exe')
FB_bloomberg_URL="https://www.bloomberg.com/quote/FB:US"
driver.get(FB_bloomberg_URL)

eList = driver.find_elements_by_class_name('link__f5415c25')
hrefList = []
for e in eList:
    hrefList.append(e.get_attribute('href'))

for href in hrefList:
    print(href)
    # iterating through all the board members here #<== changed below
    driver.get(href)
    # you can add WebDriver wait for the below item to be displayed 
    # so that the script will wait until page loaded successfully with this element
    boardmembership_table=driver.find_elements_by_xpath('//*[@id="root"]/div/section/div[5]')[0]
    boardmembership_table.text

Answer 2

基本上，只需将第二块连接到for循环下的第一块：

import sys
from selenium import webdriver
driver = webdriver.Firefox()

FB_bloomberg_URL="https://www.bloomberg.com/quote/FB:US"
driver.get(FB_bloomberg_URL)

eList = driver.find_elements_by_class_name('link__f5415c25')
hrefList = []
for e in eList:
    hrefList.append(e.get_attribute('href'))

for href in hrefList:
    --print(href)
    driver.get(href)    
    boardmembership_table=driver.find_elements_by_xpath('//*[@id="root"]/div/section/div[5]')[0]
    boardmembership_table.text

额外收获:下面是如何使用regex (import re)从URL中提取人名，并将董事会成员表添加到字典中。

result_dict = {}
regex = r"\/people\/\d+-(.*)$"
for href in hrefList:
    driver.get(href)    
    boardmembership_table=driver.find_elements_by_xpath('//*[@id="root"]/div/section/div[5]')[0]    
    matches = re.finditer(regex, href, re.MULTILINE)
    for matchNum, match in enumerate(matches, start=1):        
        result_dict[match.group(1)] = boardmembership_table.text

这会让你领先一步。
