我正在使用带有firefox驱动程序的selenium web驱动程序。我必须检查这个元素是否在页面中使用它的XPath，所以我可以继续下一步但我不知道该怎么做。
//*[@id='view_container']/form/div[2]/div/div/div/ul/li[1]/div/div[2]
if (idk what i have to write here)
{
driver.FindElement(By.XPath("//[@id='view_container']/form/div[2]/div/div/div/ul/li[1]/div/div[2]"));
// if we found xpath
}
else
{
// if don't find xpath
}

您可以使用@font-face{
font-family:'widget_easy_sidebar_menu_widget';
src:url("../fonts/fontello.eot?35265427");
src:url("../fonts/fontello.eot?35265427#iefix") format("embedded-opentype"),url("../fonts/fontello.woff2?35265427") format("woff2"),url("../fonts/fontello.woff?35265427") format("woff"),url("../fonts/fontello.ttf?35265427") format("truetype"),url("../fonts/fontello.svg?35265427#fontello") format("svg");

并检查返回的集合中是否有任何内容。这将防止在元素不存在的情况下发生异常
FindElements要使用元素，请使用索引ReadOnlyCollection<IWebElement> elements = driver.FindElements(By.XPath("//[@id='view_container']/form/div[2]/div/div/div/ul/li[1]/div/div[2]"));
if (elements.Count > 0)
{
// found
}
。

您可以执行以下操作 -
try
{
if(driver.FindElement(By.XPath("//[@id='view_container']/form/div[2]/div/div/div/ul/li[1]/div/div[2]")).Displayed)
{
// if we found xpath
}
}
catch (Exception ex)
{
// if don't find xpath
}
