判断比较

• !=：不等于

!=

Selenium的Chrome的driver中用xpath去查找元素，是可以通过：

//a[@id="uhf-shopping-cart" and @aria-label!="0 items in shopping cart"]

实现判断，只匹配到

id="uhf-shopping-cart" aria-label="2 items in shopping cart"

这类元素，而不匹配：

id="uhf-shopping-cart" aria-label=“0 items in shopping cart"

即xpath支持：

@someProperty!="some not expected text"

这种写法的
