如何用asp.net读取xml文件中的某个值？
我有下面这个myalexa.xml文件,请问如何用asp.net读取下面文件中的 <POPULARITY   URL= "xxxx.net/ "   TEXT= "5980955 "/> 这行,并显示出来?谢谢大家(我是用c#的)我搞来搞去都总是出错,因为myalexa.xml文件 <POPULARITY   URL= "xxxx.net/ "   TEXT= "5980955 "/> 这行,不一定每次都会有,有时有,有时没有,请大家帮忙看看如何写才会判断，如果存在就显示为：存在:xxxx.net   值是:5980955   不存在就显示为：存在:xxxx.net   值是:０  
谢谢大家
