我有下面的代码。我试图了解
re.compile('ctl(\d\d)_MainContent_ctl(\d\d)_DataDetails_ctl(\d\d)_trGBKItem')
确实是，为什么
tstsoup.find_all('tr', tstgradebook_row_id)
返回一个空列表。
我在下面提供了一个tstsoup示例，在其中我用“ ...”替换了一些块，以便将其发布。它来自
tstsoup = BeautifulSoup(driver.page_source)
此代码遵循仓库中的代码
https://github.com/AlbanyCompSci/aeries-api
在Gradebook.py文件中的。我正在用它来尝试编写脚本来登录并提高我的孩子的高中成绩。
代码：
import pandas as pd
import numpy as np
import os
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
Options
options = Options()
chrome_options = Options()
options.add_argument('headless') #downlod Chrome driver.exe
driver = webdriver.Chrome(executable_path=os.path.abspath("chromedriver"), chrome_options=chrome_options)
import re, dateutil.parser
from bs4 import BeautifulSoup
# tstsoup
tstgradebook_row_id = {'id': re.compile('ctl(\d\d)_MainContent_ctl(\d\d)_DataDetails_ctl(\d\d)_trGBKItem')}
# tstgradebook_row_id
tstgradebook_rows = tstsoup.find_all('tr', tstgradebook_row_id)
tstgradebook_rows
输出：
[]
样本数据：
tstsoup

答案 0 :(得分：0)
我发现我要查找的ID的模式已更改。现在看起来像'ctl（\ d \ d）_MainContent_subGBS_DataDetails_ctl（\ d \ d）_trGBKItem'，如果使用该模式，我将获得正确的源代码块。
