Question

我正在尝试从名为Correios的网站获取所有数据，在此网站中，我需要处理一些下拉菜单，这些下拉菜单存在一些问题，例如：它正在返回带有一串空字符串的列表。

chrome_path = r"C:\\Users\\Gustavo\\Desktop\\geckodriver\\chromedriver.exe"

driver = webdriver.Chrome(chrome_path)

lista_x = []

driver.get("http://www2.correios.com.br/sistemas/agencias/")

driver.maximize_window()

dropdownEstados = driver.find_elements_by_xpath("""//*[@id="estadoAgencia"]""")

optEstados = driver.find_elements_by_tag_name("option")

for valores in optEstados:

    print(valores.text.encode())

我从中得到的是：

Answer 1

要检索从文本中的所有<options>的的下拉与ID为estadoAgencia，因为它是一个<select>标签那将是更容易和有效地使用相关联的方法<select>标签，您可以采用如下方案：代码块：estado_select = Select(driver.find_element_by_id('estadoAgencia'))for opt in estado_select.options:&nbsp; &nbsp; print(opt.get_attribute('innerHTML'))控制台输出：ACREALAGOASAMAPÁAMAZONASBAHIACEARÁDISTRITO FEDERALESPÍRITO SANTOGOIÁSMARANHÃOMINAS GERAISMATO GROSSO DO SULMATO GROSSOPARÁPARAÍBAPERNAMBUCOPIAUÍPARANÁRIO DE JANEIRORIO GRANDE DO NORTERONDÔNIARORAIMARIO GRANDE DO SULSANTA CATARINASERGIPESÃO PAULOTOCANTINS
