Selenium 中的刮擦问题。它不刮

Question

我想得到轮数（14、15、16、17 等），然后只刮数字，没有“.ROUND”。我写了一个基本版本和一个更好的版本，但它们不起作用。我没有收到错误，但我收到了>>>>（没有任何文字）。怎么办？

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

wait = WebDriverWait(driver, 20)

Values_PremierLeague = []

driver.get("https://www.betexplorer.com/soccer/england/premier-league/fixtures/")

wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, "th.h-text-left")))

for PremierLeague in driver.find_elements(By.CLASS_NAME, "th.h-text-left"):
    PremierLeague_text = PremierLeague.text
    Values_PremierLeague.append(tuple([PremierLeague_text]))
    print(PremierLeague_text)
driver.close

或

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

wait = WebDriverWait(driver, 20)

Values_PremierLeague = []

driver.get("https://www.betexplorer.com/soccer/england/premier-league/fixtures/")

wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".table-main__datetime")))

for PremierLeague in driver.find_elements(By.XPATH, "//*[@class='h-text-left' and contains(text(),'Round')]"):
    PremierLeague_text = PremierLeague.text
    number = re.findall(r'\d+', s)
    Values_PremierLeague.append(tuple([number]))
    print(number)
driver.close

更新

CREATE TABLE "BASE_Giornate" (
    "ID_Round"  INTEGER,
    "Number_Round"  INTEGER,
    "Id_Tournment"  INTEGER,
    PRIMARY KEY("ID_Giornata" AUTOINCREMENT)
);

而且代码已经在工作了

sqlite_insert_query_PremierLeague = 'INSERT INTO BASE_Giornate (Number_Round) VALUES (?);'
cursor.executemany(sqlite_insert_query_PremierLeague, Values_PremierLeague)
count_squadre_PremierLeague = cursor.rowcount
con.commit()  

Answer 1

driver.get("https://www.betexplorer.com/soccer/england/premier-league/fixtures/")

wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".table-main__datetime")))

for PremierLeague in driver.find_elements(By.XPATH, "//*[@class='h-text-left' and contains(text(),'Round')]"):
    PremierLeague_text = PremierLeague.text
    number = re.findall(r'\d+', PremierLeague_text)
    Values_PremierLeague.append(tuple([number]))
    print(number)

不知道你所说的数字是什么意思，也不知道你为什么想要元组。但是您遇到了一个问题，您从未使用过 PremierLeague_text

输出：

['13']
['14']
['15']
['16']
['17']
['18']
['19']
['20']
