Question

我想在具有xml下载链接的网页中找到所有超链接并在循环中下载它们。存在当点击所述超链接时出现的形式，并且需要填写以继续下载。我在网页中与此xml文件相关的元素的可见性方面遇到问题，但是我收到以下错误：

“selenium.common.exceptions.ElementNotInteractableException：消息：元素不可见“

我特此附上代码，任何纠正此问题的建议将不胜感激。

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

fp = webdriver.FirefoxProfile()

fp.set_preference("browser.download.folderList", 2)
fp.set_preference("browser.download.manager.showWhenStarting", False)
fp.set_preference("browser.download.dir", "F:\Projects\Poli_Map\DatG_Py_Dat")
fp.set_preference("browser.helperApps.neverAsk.saveToDisk", "text/xml")

driver = webdriver.Firefox(firefox_profile=fp)

m = 'xml'
driver.get('https://data.gov.in/catalog/variety-wise-daily-market-prices-data-cauliflower')
wait = WebDriverWait(driver, 10)

elem = driver.find_element_by_xpath("//*[@href]")
elem.send_keys("xml")
elem.send_keys(Keys.RETURN)

wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".list-recent-events li")))

assert m in driver.page_source
for link in elem:
    link.click()


    class FormPage(object):
        def fill_form(self, data):
            driver.execute_script("document.getElementById('edit-download-reasons-non-commercial').click()")
            driver.execute_script("document.getElementById('edit-reasons-d-rd').click()")
            driver.find_element_by_xpath('//input[@name = "name_d"]').send_keys(data['name_d'])
            driver.find_element_by_xpath('//input[@name = "mail_d"]').send_keys(data['mail_d'])
            return self

        def submit(self):
            driver.execute_script("document.getElementById('edit-submit').click()")


    data = {
        'name_d': 'xyz',
        'mail_d': 'xyz@outlook.com',
    }

    time.sleep(3)
    FormPage().fill_form(data).submit()

您必须只找到XML而不是所有超链接。您的定位器//*[@href]正在查找所有HREF链接。使用以下代码

#locate all the links which have xml 
allelements = driver.find_elements_by_xpath("//a[text()='xml']")

# Iterate all links one by one
for element in allelements:
    element.click()
    class FormPage(object):
        def fill_form(self, data):
            driver.execute_script("document.getElementById('edit-download-reasons-non-commercial').click()")
            driver.execute_script("document.getElementById('edit-reasons-d-rd').click()")
            driver.find_element_by_xpath('//input[@name = "name_d"]').send_keys(data['name_d'])
            driver.find_element_by_xpath('//input[@name = "mail_d"]').send_keys(data['mail_d'])
            return self

        def submit(self):
            driver.execute_script("document.getElementById('edit-submit').click()")


    data = {
        'name_d': 'xyz',
        'mail_d': 'xyz@outlook.com',
    }
    time.sleep(5)
    FormPage().fill_form(data).submit()

    #It opens the download link in new tab So below code again switch back to parent window itself
    window_before = driver.window_handles[0]
    driver.switch_to_window(window_before)
