【问题描述】：

# importing package

from selenium import webdriver

# setting the path

PATH = "C:\Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(PATH)
options = webdriver.ChromeOptions
options.headless = True

driver.get("https://www.craispesaonline.it/provincia/treviso")

# x path for Address and Postal Code

x = ('//address//p[@class="text-lowercase m-0 ng-binding"]')
search = driver.find_elements_by_xpath(x)

# retrieving the output in a text file

with open("Italy_Scrape.txt", "a") as f:
    for i in search:
        print("PostalCode :" + i.text, file=f)
        print("----------------------------------------------------------------------------", file=f)

driver.quit()

获取邮政地址的代码。在上面的代码中，我使用的是无头铬的硒。只需要该代码来获取可以送货的商店的邮政编码。

【解决方案1】：

页面需要时间才能完全加载，因此您无法获得所需的值。

获取所有邮政编码诱导WebDriverWait()，等待visibility_of_all_elements_located()

要从元素中获取最后一个子元素，您可以诱导 javascript 执行器或分割线获取唯一的邮政编码。

driver.get("https://www.craispesaonline.it/provincia/treviso")
search=WebDriverWait(driver,20).until(EC.visibility_of_all_elements_located((By.XPATH,'//address//p[@class="text-lowercase m-0 ng-binding"]')))
for postcode in search:
    print(driver.execute_script('return arguments[0].lastChild.textContent;', postcode))

您需要导入以下库。

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

控制台输出：

0422/710092
 0422 452388
 0422/958833
 0423/689003
 0422/853881

使用splitlines() 输出相同

driver.get("https://www.craispesaonline.it/provincia/treviso")
search=WebDriverWait(driver,20).until(EC.visibility_of_all_elements_located((By.XPATH,'//address//p[@class="text-lowercase m-0 ng-binding"]')))
for postcode in search:
    print(postcode.text.splitlines()[-1].split("|")[-1].strip()) #last element which is postcode

【解决方案2】：

要完成前面的答案，您可以通过一个 XPath 表达式获取可以送货的商店的邮政编码：

//div[@class="row province-cms-content-store-row ng-scope"][./div[@ng-if="store.shippingEnabled == true"]]//meta[@itemprop="postalCode"]/@content

硒代码：

driver.get("https://www.craispesaonline.it/provincia/treviso")
postcodes = WebDriverWait(driver,20).until(EC.visibility_of_all_elements_located((By.XPATH,'//div[@class="row province-cms-content-store-row ng-scope"][./div[@ng-if="store.shippingEnabled == true"]]//meta[@itemprop="postalCode"]'))).get_attribute("content")

输出：29 个邮政编码

['31038']
['31038']
['31047']
['31050']
['31030']
...

【解决方案3】：

要提取邮政编码，仅针对可以送货的商店，您可以为visibility_of_all_elements_located() 诱导WebDriverWait，您可以使用以下xpath 基于Locator Strategy：

使用CSS_SELECTOR：

driver.get("https://www.craispesaonline.it/provincia/treviso")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='cl-accept']"))).click()
driver.execute_script("return arguments[0].scrollIntoView(true);", WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//h2[contains(., 'Potrai scegliere di ricevere la tua spesa in due modi:')]"))))
addresses = [my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//input[@value='Consegna']//preceding::address[1]//p[@class='text-lowercase m-0 ng-binding']")))]
for address in addresses:
    print(re.findall(r"\b\d{5}\b", address))

控制台输出：

['31038']
['31038']
['31047']
['31050']
['31030']
['31031']
['31034']
['31014']
['31035']
['31010']
['31010']
['31036']
['31037']
['31037']
['31050']
['31050']
['31044']
['31044']
['31044']
['31044']
['31044']
['31023']
['31058']
['31040', '81743']
['31049']
['31050']
['31020']
['31040']
['31040']

注意：您必须添加以下导入：

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