将网络抓取的表格放入excel（selenium，python）

Question

我想将表格及其标题放入 excel 中。我尝试了很多东西，但我似乎无法弄清楚如何在 excel 中正确显示它。下面还有一张图片展示了我希望它如何理想地显示。先感谢您。from selenium import webdriverfrom selenium.webdriver.support.ui import Selectfrom selenium.webdriver.common.keys import Keysfrom selenium.webdriver.support.ui import WebDriverWaitfrom selenium.webdriver.common.by import Byfrom selenium.webdriver.support import expected_conditions as ECdriver = webdriver.Chrome("drivers/chromedriver")driver.get("https://web3.ncaa.org/hsportal/exec/hsAction")Select(WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "state")))).select_by_visible_text("New Hampshire")driver.find_element_by_xpath("//input[@id='city']").send_keys("Moultonborough")driver.find_element_by_xpath("//input[@id='name']").send_keys("Moultonborough Academy")driver.find_element_by_xpath("//input[@value='Search']").click()WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@name='hsCode']"))).click()print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//table[@id='approvedCourseTable_1']//th[@class='header']")))])table = ([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "table#approvedCourseTable_1.tablesorter")))])with open('out.csv', 'w', newline='') as csvfile:    writer = csv.writer(csvfile)    writer.writerow(table)出于某种原因，在使用 table#approvedCourseTable_1.tablesorter 时将表格抓取到 excel 仅显示“课程”，仅此而已。当我将标题和表格内容分开时，我可以将它们分别抓取到 excel，但不能一起抓取。此外，当我设法将其抓取到 excel 时，表格内容没有正确排列。x = ([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "table#approvedCourseTable_1 th.header")))])y = ([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "table#approvedCourseTable_1 td")))])如果可能的话，我希望它像这样显示：

Answer 1

我有这个使用 Selenium/Python 的工作。试试下面的代码示例，

from selenium import webdriver

from selenium.webdriver.support.ui import Select

from selenium.webdriver.common.keys import Keys

from selenium.webdriver.support.ui import WebDriverWait

from selenium.webdriver.common.by import By

from selenium.webdriver.support import expected_conditions as EC

import csv

csvFile = open('out.csv', 'w')

writer = csv.writer(csvFile)

driver = webdriver.Chrome("drivers/chromedriver")

driver.get("https://web3.ncaa.org/hsportal/exec/hsAction")

Select(WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "state")))).select_by_visible_text("New Hampshire")

driver.find_element_by_xpath("//input[@id='city']").send_keys("Moultonborough")

driver.find_element_by_xpath("//input[@id='name']").send_keys("Moultonborough Academy")

driver.find_element_by_xpath("//input[@value='Search']").click()

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@name='hsCode']"))).click()

print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//table[@id='approvedCourseTable_1']//th[@class='header']")))])

#table = ([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "table#approvedCourseTable_1.tablesorter")))])

table_header = driver.find_element_by_xpath("(//table[@id='NcaaCrs_ApprovedCategory_All']//td[@class='hs_tableHeader'])[1]")

print(table_header.text)

writer.writerow(table_header.text)

#Find All Approved Categories

approved_Categories = driver.find_elements_by_xpath("//div[contains(@id,'NcaaCrs_ApprovedCategory_')]")

for i in range(len(approved_Categories)):

    cateogry_header = driver.find_element_by_xpath("//div[contains(@id,'NcaaCrs_ApprovedCategory_"+str(i+1)+"')]//td[@class='hs_tableHeader']")

    print(cateogry_header.text)

    writer.writerow(cateogry_header.text)

    #Find Course table header and rows

    course_headers = driver.find_elements_by_xpath("//table[contains(@id,'approvedCourseTable_"+str(i+1)+"')]/thead//th")

    header_val = []

    for headers in course_headers:

        header_val.append(headers.text)

    print(header_val)

    writer.writerow(header_val)

    course_rows = driver.find_elements_by_xpath("//table[@id='approvedCourseTable_"+str(i+1)+"']//tbody/tr")

    for j in range(len(course_rows)):

        row_values = driver.find_elements_by_xpath("//table[@id='approvedCourseTable_"+str(i+1)+"']//tbody/tr["+str(j+1)+"]/td")

        row_val = []

        for row in row_values:

            row_val.append(row.text)

        print(row_val)

        writer.writerow(row_val)

csvFile.close()

driver.quit()

CSV 输出将是这样的，
