Python Beautifulsoup / 从跨度请求文本

Question

我正在尝试使用 beautifulsoup 或来自此 Facebook 页面https://www.facebook.com/marketplace/item/1612977352197759/的请求来提取文本

文字是物品描述，地图前的文字： 这是我到目前为止尝试过但没有工作的方法：

import requests
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from lxml import html

opt = Options()
opt.add_argument("--disable-infobars")
opt.add_argument("start-maximized")
# Pass the argument 1 to allow and 2 to block
opt.add_experimental_option("prefs", {
        "profile.default_content_setting_values.media_stream_mic": 2,
        "profile.default_content_setting_values.media_stream_camera": 2,
        "profile.default_content_setting_values.geolocation": 2,
        "profile.default_content_setting_values.notifications": 2
    })
global driver
driver = webdriver.Chrome(chromedriver)


driver.get('https://www.google.com')

page = requests.get('https://www.facebook.com/marketplace/item/1612977352197759/?ref=messenger_banner')
tree = html.fromstring(page.content)
print(tree)
link = tree.xpath("//span[contains(string(),'hello')]")
print(link)

Answer 1

试试这个：

import requests
from bs4 import BeautifulSoup
import re
page = requests.get('https://www.facebook.com/marketplace/item/1612977352197759/?ref=messenger_banner')
soup = BeautifulSoup(page.text,'lxml')
span = soup.find("span",string=re.compile(".*hello.*"))
print(span)

如果可行，请告诉我。
