python - 如何使用 Selenium Python 从 XML URL 中按 tagName 提取元素

Question

我正在尝试通过此 XML URL http://www.rssmix.com/u/8287461/rss.xml 中的标题等标签名称查找元素但无法正常工作，请帮忙

它只是打印一张空白页，没有其他内容

browser.get("http://www.rssmix.com/u/8287461/rss.xml")
time.sleep(10)
title = browser.find_elements_by_tag_name('title')
description = browser.find_elements_by_tag_name('description')
link = browser.find_elements_by_tag_name('link')
for p_title, p_description, p_links in zip(title, description, link):
    title_s = p_title.text
    description_s = p_description.text
    link_s = p_links.text
    print (title_s + "\t"  + description_s +  "\t"  + link_s + "\n")

Answer 1

根据您的问题，您想要从 XML URL 中提取标签，您可以使用:

• fromstring() 方法和
• iter() 方法

来自Python xml.etree.ElementTree — The ElementTree XML API 以及Selenium，如下所示:

• 代码块:

  # -*- coding: UTF-8 -*-
  from selenium import webdriver
  import xml.etree.ElementTree as ET
  
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_argument('disable-infobars')
  driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get("http://www.rssmix.com/u/8287461/rss.xml")
  root = ET.fromstring(driver.page_source)
  print("Titles are : ")
  for neighbor1 in root.iter('title'):
      print(neighbor1.text)
  print("Descriptions are : ")
  for neighbor2 in root.iter('description'):
      print(neighbor2.text)
  print("Links are : ")
  for neighbor3 in root.iter('link'):
      print(neighbor3.text)
