# importing packagefrom selenium import webdriver# setting the pathPATH = "C:\Program Files (x86)\chromedriver.exe"driver = webdriver.Chrome(PATH)options = webdriver.ChromeOptionsoptions.headless = Truedriver.get("https://www.craispesaonline.it/provincia/treviso")# x path for Address and Postal Codex = ('//address//p[@class="text-lowercase m-0 ng-binding"]')search = driver.find_elements_by_xpath(x)# retrieving the output in a text filewith 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 chrome 的 selenium。需要代码以仅获取可以送货的商店的邮政编码。

Answer 1

该页面需要时间才能完全加载，因此您无法获得您想要的值。

获取所有邮政编码 Induce WebDriverWait() 和 wait for 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 执行程序或分割线来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

 0423/451941

 0422/912384

 0423/620803

 0423/621383

使用splitlines()的相同输出

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

Answer 2

要完成前面的答案，您可以使用一个 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']

...

Answer 3

要仅提取可以送货的商店的邮政编码，您可以诱导WebDriverWait并且visibility_of_all_elements_located()您可以使用以下内容xpath基于定位策略：

• 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
