如何使用 selenium headless 从 div 类中提取文本

问题描述

我正在尝试从以下 div 标签中提取0%":

I'm trying to pull out the "0%" from the following div tag:

<div class="sem-report-header-td-diff ">0%</div>

我目前的代码是:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument('--headless')
driver = webdriver.Chrome(executable_path='mypath/chrome.exe',
                      chrome_options=options)

url = 'https://www.semrush.com/info/burton.com'
driver.get(url)
driver.implicitly_wait(2)
change_elements = driver.find_elements_by_xpath(xpath='//div[@class="sem-report-header-td-diff "]')

不知道我做错了什么.这适用于 href 标签，但不适用于此.

not sure what I'm doing wrong. This works with href tags, but its not working for this.

推荐答案

根据您共享的 HTML，提取文本 0% 需要使用方法 get_attribute("innerHTML")，您可以使用以下任一解决方案:

As per the HTML you have shared to extract the text 0% you need to use the method get_attribute("innerHTML") and you can use either of the following solutions:

• css_selector:

myText = driver.find_element_by_css_selector("div.sem-report-header-td-diff").get_attribute("innerHTML")

xpath:

myText = driver.find_element_by_xpath("div[@class='sem-report-header-td-diff']").get_attribute("innerHTML")
