我想从以下站点中提取链接,但其中确实包含分页: 我想在MoreInfo Button下提取链接:
我正在使用以下代码段:
import time
import requests
import csv
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 selenium.webdriver.common.action_chains import ActionChains
import re
browser = webdriver.Chrome()
time.sleep(5)
browser.get('https://www.usta.com/en/home/play/facility-listing.html?searchTerm=&distance=5000000000&address=Palo%20Alto,%20%20CA')
wait = WebDriverWait(browser,15)
def extract_data(browser):
links = browser.find_elements_by_xpath("//div[@class='seeMoreBtn']/a")
return [link.get_attribute('href') for link in links]
element = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.XPATH, "//a[@class='glyphicon glyphicon-chevron-right']")))
max_pages = int(re.search(r'\d+ de (\d+)', element.text).group(1), re.UNICODE)
# extract from the current (1) page
print("Page 1")
print(extract_data(browser))
for page in range(2, max_pages + 1):
print("Page %d" % page)
next_page = browser.find_element_by_xpath("//a[@class='glyphicon glyphicon-chevron-right']").click()
print(extract_data(browser))
print("-----")
当我运行上面的脚本时,我得到了这个错误**(我对正则表达式不太了解,也只是在探索这个概念)**:
Traceback (most recent call last):
File "E:/Python/CSV/testingtesting.py", line 29, in <module>
max_pages = int(re.search(r'\d+ de (\d+)', element.text).group(1), re.UNICODE)
AttributeError: 'NoneType' object has no attribute 'group'
如果可能的话,请给我建议解决方案。我以某种方式设法使用等待并单击分页链接来提取链接。但是它花费的时间增加了将近13秒的等待时间
