内容图文

我用硒写了一个Python脚本来刮掉这个城市.使用反向查找从谷歌地图拉链.到目前为止它运作良好.我无法满足的唯一要求是：在搜索框中输入地址后,有时会出现一些建议,如下拉选项.它默认选择第一个.如果我想从建议中选择第二个,我就会陷入困境.

这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()

我正在谈论的建议下拉是这样的：
image_link

顺便说一下,我试图从建议下拉列表中选择第二个选项的xpath也在我的脚本中给出,此脚本此时显示为灰色.

解决方法:

我很可能不能用xpath这样做,因为我发现页面变化非常快,元素变得很陈旧.但是我可以用类来做：

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

您可以对所选元素执行click事件,如下所示：

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