Selenium 只返回一个空列表 [英] Selenium only returns an empty list

问题描述

我正在尝试从 betfair.com 抓取足球队的名称，但无论如何，它都会返回一个空列表.这是我最近尝试过的.

I'm trying to scrape football team names from betfair.com and no matter what, it returs an empty list. This is what I've tried most recently.

from selenium import webdriver
import pandas as pd

driver = webdriver.Chrome(r'C:\Users\Tom\Desktop\chromedriver\chromedriver.exe')
driver.get('https://www.betfair.com/exchange/plus/football')

team = driver.find_elements_by_xpath('//*[@id="main-wrapper"]/div/div[2]/div/ui-view/div/div/div/div/div[1]/div/div[1]/bf-super-coupon/main/ng-include[3]/section[1]/div[2]/bf-coupon-table/div/table/tbody/tr[1]/td[1]/a/event-line/section/ul[1]/li[1]')

print(team)

推荐答案

你应该使用 WebDriverWait.此外，您应该使用相对 xPath，而不是绝对 xPath.您正在为单个元素使用 find_elements 的另一件事.

You should use WebDriverWait. Also, you should use a relative xPath, not absolute xPath. One more thing you are using find_elements for a single element.

这里我正在打印所有团队

Here I'm printing all the teams

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

driver = webdriver.Chrome(r"C:\Users\Tom\Desktop\chromedriver\chromedriver.exe")
driver.get('https://www.betfair.com/exchange/plus/football')
teams = WebDriverWait(driver, 10).until(EC.presence_of_all_elements_located((By.XPATH, '//*[@id="main-wrapper"]//ul[@class="runners"]/li')))
print([i.text for i in teams])

输出:
