如何在pythonwebdriver中等待CSS和XPath选择器的组合?

您可以创建自定义方法:

def find_element_by_combo(self, ancestor_locator, descendant_locator, timeout=10, index=0):
    # Getting list of ancestors
    try:
        ancestors =  wait(self, timeout).until(EC.presence_of_all_elements_located(ancestor_locator))
    except:
        return None
    # Getting descendant
    for ancestor in ancestors:
        if ancestor.find_elements(*descendant_locator):
            return ancestor.find_elements(*descendant_locator)[index]

使用方法如下

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

Chrome.find_element_by_combo = find_element_by_combo

driver = Chrome()
driver.get(URL)
driver.find_element_by_combo(('css', '.files tbody tr:first-child'), ('xpath', './th[text()="filename"]'))
