Выбор опции в оптгруппе с селеном и питоном

Я хотел бы выбрать значение из этой optgroup, которое затем должно дать мне выпадающий список ссылок. 

<div class="searchbar">
    <select id="q" multiple="" tabindex="-1" class="select2-hidden-accessible" aria-hidden="true">
    <option></option>
    <option class="q-all-text" value="al:all">Search all text</option>

    <optgroup label="Business Type">
        <option value="bt:Buyer">Buyer</option>
        <option value="bt:Farmer/Rancher">Farmer/Rancher</option>
        <option value="bt:Farmers Market">Farmers Market</option>
        <option value="bt:Fishery">Fishery</option>
        <option value="bt:Food Bank">Food Bank</option>
    </optgroup>

Вот мой код: 

driver = webdriver.Chrome('/path/to/chromedriver')
driver.get("https://foodmarketmaker.com/main/mmsearch")
iframe = driver.find_element_by_tag_name("iframe")
driver.switch_to.frame(iframe)

select  = Select(driver.find_element_by_class_name("select2-hidden- accessible"))
select.select_by_value("bt:Farmer/Rancher")
links = driver.find_elements_by_tag_name('a')
print(links)
for link in links:
    print(link.get_attribute('href'))

Я либо получаю исключение, что элемент не существует, либо когда я получаю доступ по индексу, я получаю исключение ElementNotVisibleException из-за того, что атрибут aria-hidden равен true. Есть ли способ обойти это?

В соответствии с HTML, которым вы поделились, чтобы распечатать все опции, которые вы должны заставить WebDriverWait переключиться на нужный кадр, затем нажмите Поле поиска для параметры должны отображаться следующим образом:

  • Кодовый блок: 

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

options = Options()
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get("https://foodmarketmaker.com/main/mmsearch")
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@src='https://search.foodmarketmaker.com']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='searchbar']//input[@class='select2-search__field' and @placeholder='start typing to search']"))).click()
links = driver.find_elements_by_xpath("//li[@class='select2-results__option' and @aria-label='Business Type']/strong//following::ul[1]//li")
for link in links:
    print(link.get_attribute('innerHTML'))

select - это не тот узел, который вам нужно обработать, так как он не виден.

Попробуйте следующий код, чтобы получить требуемый вывод: 

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


driver = web.Chrome('/path/to/chromedriver')
driver.get("https://foodmarketmaker.com/main/mmsearch")
iframe = driver.find_element_by_tag_name("iframe")
driver.switch_to.frame(iframe)

wait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, '//section[@id="search-right"]//input[@placeholder="start typing to search"]'))).click()
wait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, '//li[.="Bass"]'))).click()

links = wait(driver, 10).until(EC.presence_of_all_elements_located((By.XPATH, '//section[@id="search-results"]//a[.//*[name()="svg"]]')))

for link in links:
    print(link.get_attribute('href'))

P.S. Вам необходимо заменить текстовое значение узла li в '//li[.="Bass"]' XPath обязательным параметром
