python - 如何从动态网站 python selenium 中检索表

Question

我想从动态网站的表格中检索所有信息，我有以下代码:

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.common.exceptions import TimeoutException
import sys
reload(sys)
import re
import csv
from time import sleep
sys.setdefaultencoding('utf-8') #added since it would give error for certain values when using str(i)

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')
prefs = {'profile.managed_default_content_settings.images':2}
chrome_options.add_experimental_option("prefs", prefs)
driver = webdriver.Chrome(chrome_options=chrome_options) 

maxcr = 1379
listofrows = []


url = "http://biggestbook.com/ui/catalog.html#/itemDetail?itemId=HERY4832YER01&uom=CT"
print(url) 
driver.get(url)
wait = WebDriverWait(driver,10)
# Trying to get the table 
tableloadwait = (wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, ".panel-body"))))
table = driver.find_elements_by_css_selector(".panel-body")
print(table)
RowsOfTable = table.get_attribute("tr")

但是，我不断收到错误消息，但到目前为止还没有用。如何检索表的信息？非常感谢!

错误:RowsOfTable = table.get_attribute("tr")AttributeError: 'list' 对象没有属性 'get_attribute'

Answer 1

这是获取产品详情的代码

tableloadwait = (wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, ".panel-body"))))
driver.find_element_by_xpath("//span[contains(.,'Product Details')]").click()
rows = driver.find_elements_by_xpath("//span[contains(.,'Product Details')]/ancestor::div[@class='accordion-top-border']//tr[(@ng-repeat='attr in attributes' or @ng-repeat='field in fields') and @class='visible-xs']")

for rowNum in range(len(rows)):
    print(rows[rowNum].get_attribute('innerText'))
driver.quit()

我们必须根据您的要求修剪值或打破值。

如果您想获取基于行文本的数据，请使用以下内容。

upcData = driver.find_element_by_xpath("//strong[.='UPC']/parent::td").get_attribute('innerText').replace('UPC','').replace('\n','').replace('    ','')
