问题描述
我正在尝试抓取表格并写入数据框中，他们向我显示了 typeerror.如何解决这些错误?
I am trying to scraping the table and write in a dataframe they show me a typeerror. How to resolve these errors?
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.select import Select
from selenium import webdriver
import pandas as pd
temp=[]
driver= webdriver.Chrome('C:Program Files (x86)chromedriver.exe')
driver.get("https://www.fami-qs.org/certified-companies-6-0.html")
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[title='Inline Frame Example']")))
headers=WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//table[@id='sites']//thead"))).text
rows=WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//table[@id='sites']//tbody"))).text
temp.append(rows)
df = pd.DataFrame(temp,columns=headers)
print(df)
在标题中我传递数据 FAMI-QS Number ... Expiry date 而在行中我将传递 FAM-0694 ... 2022-09-04
In headers I pass the data FAMI-QS Number ... Expiry date while in rows I will pass the FAM-0694 ... 2022-09-04
推荐答案
刮取所有列中的所有数据，您需要引入 WebDriverWait 用于 visibility_of_element_located() To scrape all the data from all the columns you need to induce WebDriverWait for the visibility_of_element_located() of the 代码块: Code Block: 控制台输出: Console Output: 这篇关于将表抓取并写入数据帧显示我 TypeError的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！code> 元素，提取 outerHTML，使用
read_html() 读取outerHTML，您可以使用以下定位器策略:<table> element, extract the outerHTML, read the outerHTML using read_html() and you can use the following Locator Strategies:driver.get("https://www.fami-qs.org/certified-companies-6-0.html")
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[title='Inline Frame Example']")))
data = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "table#sites"))).get_attribute("outerHTML")
df = pd.read_html(data)
print(df)
driver.quit()
