我继续从以下代码和网站中获得关于元素难以理解的错误。我已经附上了html截图和我的完整代码。希望有人可以帮助我。我已经尝试过等待按钮的等待,但是它不起作用。我需要将每个成绩单下载到我的文件夹中,并且有必要按日期搜索它们,这就是为什么我要使用包含日期的xpath
months = ['January', 'February', 'March', 'April', 'May', 'June',
'July', 'August', 'September', 'October', 'November', 'December']
years = ['1983', '1982', '1981', '1980', '1979', '1978', '1977', '1976', '1975', '1974',

driver.get(f'https://fraser.stlouisfed.org/title/677')
driver.set_page_load_timeout(15)
for y in years:
for m in months:
pdf_links = []
xpath = "//*[contains(text(), '"+m+"') and contains(text(), '"+y+"')]"
period = driver.find_element_by_xpath(xpath)
#period = WebDriverWait(driver, 5).until(EC.element_to_be_clickable((By.XPATH, xpath)))
#driver.execute_script("arguments[0].click();", period)
period.click()
driver.quit()
答案 0 :(得分:0)
您可以尝试使用以下xpath。
添加以下导入。
driver = webdriver.Chrome(
executable_path=os.path.join(GenericMethods.get_full_path_to_folder('drivers'), "chromedriver.exe"),
chrome_options=chrome_options)
months = ['January', 'February', 'March', 'April', 'May', 'June',
'July', 'August', 'September', 'October', 'November', 'December']

driver.get(f'https://fraser.stlouisfed.org/title/677')
driver.set_page_load_timeout(15)
pdf_links=[]
search = driver.find_element_by_class_name('list-search.form-control.input-sm')
for y in years:
for m in months:
print (m + "-" + y)
search.clear()
search.send_keys(y)
WebDriverWait(driver, 30).until(EC.presence_of_element_located((By.XPATH, "//span[contains(., '" + y + "')]/parent::a")))
xpath = "//span[contains(., '" + m + "') and contains(., '" + y + "')]/parent::a"
elinks = driver.find_elements_by_xpath(xpath)
if len(elinks)>0:
print(elinks[0].get_attribute('href'))
pdf_links.append(elinks[0].get_attribute('href'))
driver.quit()
print(pdf_links)
并如下更新脚本</ p>
