Selenium无法从asp页面获得任何标签，如“表”或“a”。我也尝试过让“体”标签，在这种情况下，它承认，但如下抛出异常：为什么Selenium网络驱动程序无法从aspx网页获取'标签'？
> Unhandled Exception: OpenQA.Selenium.StaleElementReferenceException:

> driverCommandToExecu te, Dictionary`2 parameters) at
> OpenQA.Selenium.Remote.RemoteWebElement.GetAttribute(String
> attributeName)
我用C＃代码：
FirefoxProfile firefoxProfile = new FirefoxProfile(@"C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles\rwyq8vbx.default");
IWebDriver driver = new FirefoxDriver(new FirefoxBinary(@"C:\Program Files (x86)\Mozilla Firefox\firefox.exe"), firefoxProfile);
driver.Manage().Window.Maximize();
driver.Navigate().GoToUrl(@"http://epmweb.apac.bbc.com/pwa/_layouts/pwa/mytssummary.aspx");
System.Threading.Thread.Sleep(10000);
driver.SwitchTo().DefaultContent();
List<IWebElement> frameset = driver.FindElements(By.TagName("iframe")).ToList();
Console.WriteLine(frameset.Count);
foreach (var v in frameset)
{
Console.WriteLine("fName : " + v.GetAttribute("name"));
}
IWebElement[] rows = driver.FindElements(By.TagName("body")).ToArray();
Console.WriteLine(rows.Length);
foreach (var v in rows)
{
Console.WriteLine("Name : "+v.GetAttribute("id"));
}
框架指望它给零和行的长度1.
显然，当我点击查看页面源&保存该页面为html。我能够获得标签。
任何帮助，我在这里错过了什么？
编辑::我试着得到网页什么硒得到作为网页。它返回：`

但是，当我手动检查网页的源文件，它看起来正常，因为它应该是。
它不一定是**“iframe”标签**。它也可以是一个**框架**标签。您是否注意到了这种可能性？ – Subh 2015-02-11 17:47:34
也没有“框架”标签。只有在网站上运行时才能获取标签。如果我检查页面源并将其保存在本地HTML页面中，我可以获取标签。此外，它可以在网站上运行时获取身份标记，但不能识别其身份或文本。它实际上是一个内部网站。这没关系，对吧？我猜想启用了一些安全性当我使用chrome打开相同的链接时，会出现错误，“至少使用Internet Explorer版本6才能使用Project Web Access”。 – mkkhedawat 2015-02-12 05:01:22
