检索带有Selenium WebDriver和Python的动态框架名称? [英] retrieve dynamic frame names w/ Selenium WebDriver and Python?
问题描述
我需要在一个特定的数据库上运行数千个搜索，并且我正在使用Python和Selenium WebDriver对其进行自动化.事实是，包含搜索结果的框架的名称是动态生成的.该名称始终以相同的方式开头(例如，"results_frame")，然后跟着一堆每次更改的数字(例如"results_frame1298120910290").因此，基于几个小时的搜索，我尝试使用xpath:
I need to run thousands of searches on a certain database and I'm using Python and Selenium WebDriver to automate it. The thing is, the frame that contains the search results has a name that is dynamically generated. That name always begins the same way (say, "results_frame") and then it's followed by a bunch of numbers that change every time (like "results_frame1298120910290"). So, based on a few hours of googling, I tried using xpath:
framename = driver.find_elements_by_xpath("//frame[contains(@name, 'results_frame')]")
driver.switch_to_frame(framename)
不好.当我打印'framename'时，我得到的是这样:
No good. When I print 'framename', what I get is this:
[<selenium.webdriver.remote.webelement.WebElement object at 0x101206350>, <selenium.webdriver.remote.webelement.WebElement object at 0x101206390>]
代替框架的实际名称.
我还尝试使用索引(如在driver.switch_to_frame(0)，driver.switch_to_frame(1)等中)，如建议的
I've also tried using indexes (as in driver.switch_to_frame(0), driver.switch_to_frame(1), etc), as suggested here, but no good either.
那么，当动态生成框架名称时，如何检索该框架的名称?有什么想法吗?
So, how can I retrieve a frame's name when that name is dynamically generated? Any thoughts?

推荐答案
find_elements_by_xpath返回类型为WebElement的对象.您需要使用get_attribute从WebElement检索属性的值.
find_elements_by_xpath returns an object of type WebElement. You need to use get_attribute to retrieve the value of an attribute from the WebElement.
framename = driver.find_element_by_xpath("//frame[contains(@name, 'results_frame')]").get_attribute("name")
这应该返回您要查找的名称.
That should return the name you're looking for.
