python - 使用 xpath 和 LXML 或 selenium 从 HTML 表中抓取数据

问题描述

我需要从这个网站的 HTML 表中提取数据： https ://1x2.lucksport.com/result_en.shtml?dt=2019-04-12&cid=156

我将 Python、selenium 和 lxml 与 xpath 一起使用

我想提取每场比赛的赔率问题是每场比赛在两排两排：tr class="dtd2"，然后是两排：tr class="dtd1"

我需要允许提取第一行和他的下一行的 xpath

driver.get(u)
t = html.fromstring(driver.page_source)
for i in t.xpath('//*[@id="odds_tb"]/table/tbody/tr[@class="dtd2"]/td[1]/text()'):

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from bs4 import BeautifulSoup as bs
import pandas as pd
import copy

d = webdriver.Chrome()
d.get('https://1x2.lucksport.com/result_en.shtml?dt=2019-04-12&cid=156')
WebDriverWait(d, 20).until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, "#odds_tb tr[class]")))
soup = bs(d.page_source, 'lxml')
rows = soup.select('#odds_tb tr[class]')
results = []
i = 1 
headers = ['Competition', 'Date', 'Match' ,'OddsType', 'Home Win', 'Draw', 'Away Win', 'Result']

for row in rows[1:]:    
    cols = [td.text for td in row.select('td')]

    if (i % 2 == 1):
        record = {'Competition' : cols[0],
                  'Date' : cols[1],
                  'Match' : ' v '.join([cols[2], cols[6]]),
                  'OddsType' : 'average early odds',
                  'Home Win' : cols[3], 
                  'Draw' : cols[4], 
                  'Away Win' : cols[5],
                  'Result' : cols[7]}
    else:
        record['OddsType'] = 'average live odds'
        record['Home Win'] = cols[0] 
        record['Draw'] = cols[1] 
        record['Away Win'] = cols[2]
    results.append(copy.deepcopy(record))
    i+=1

df = pd.DataFrame(results, columns = headers)
df.to_csv(r'C:\Users\User\Desktop\data.csv', sep=',', encoding='utf-8-sig',index = False )
d.quit()
