面临问题从建议下拉列表中选择第二项

Question

我用python和selenium编写了一个脚本，使用反向查找从google地图中获取城市和邮政编码。到目前为止效果还不错。我唯一不能满足的要求是：在搜索框中输入地址后，有时会出现一些建议，就像一个下拉选择。它默认选择第一个。如果我想从建议中选第二个，我就卡住了。你知道吗

以下是我正在尝试的脚本：

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

search_street = ['10123 HARDISON','1006 ELEANOR ST']

def find_address(driver, wait):
    for item in range(0,2):
        driver.get("https://maps.google.com/maps?q=Houston")
        wait = WebDriverWait(driver, 10)
        input_val = wait.until(EC.presence_of_element_located((By.NAME, "q")))
        input_val.clear()
        input_val.send_keys(search_street[item])
        driver.find_element_by_id('searchbox-searchbutton').click()

        # wait.until(EC.presence_of_element_located((By.XPATH, "//div[@id='sbse6']")))
        # driver.find_elements_by_xpath("//div[@id='sbse6']")[2].click()

        wait.until(EC.presence_of_element_located((By.XPATH, "//div[@class='section-hero-header-description']")))  
        element = driver.find_element_by_xpath("//div[@class='section-hero-header-description']")
        name = driver.execute_script("return arguments[0].childNodes[3].textContent", element).strip()
        print(name)

if __name__ == '__main__':
    driver = webdriver.Chrome()
    wait = WebDriverWait(driver, 10)
    try:
        find_address(driver, wait)
    finally:
        driver.quit()

建议下拉列表的Html元素：

我说的建议下拉列表是： image_link

顺便说一句，我试图从suggestion下拉列表中选择第二个选项的xpath也出现在我的脚本中，这个脚本现在变灰了。你知道吗

Answer 1

我很可能无法使用xpath，因为我发现页面变化很快，元素很快就过时了。不过，我可以在课堂上做到：

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

search_street = ['10123 HARDISON','1006 ELEANOR ST']

def find_address(driver, wait):
    for item in range(0,2):
        driver.get("https://maps.google.com/maps?q=Houston")
        wait = WebDriverWait(driver, 10)
        input_val = wait.until(EC.presence_of_element_located((By.NAME, "q")))
        input_val.clear()
        input_val.send_keys(search_street[item])

        wait.until(EC.presence_of_element_located((By.CLASS_NAME, "suggest")))
        sleep(5) # To prevent stale element reference as the text changes.
        for element in driver.find_elements_by_class_name("suggest"):
            print (element.text)

if __name__ == '__main__':
    driver = webdriver.Chrome()
    wait = WebDriverWait(driver, 10)
    try:
        find_address(driver, wait)
    finally:
        driver.quit()

输出：

10123 Hardison Lane Houston, TX
10123 Hardison Lane Abilene, TX
10123 Hardison Road Woodburn, KY
10123 Hardison Road Charlotte, NC
10123 Hardison Road Columbia, TN
1006 Eleanor Street College Station, TX
1006 Eleanor Street Houston, TX
1006 Eleanor Street Victoria, TX
1006 Eleanor Street La Marque, TX
1006 Eleanor Street Brenham, TX

可以对所选元素执行如下单击事件：

driver.find_elements_by_class_name("suggest")[2].click()
