我有一个简单的要求，我需要获取属性xml的值：即af1。我正在使用SAXParser，这是我的xpath：a / aff / @ xml：id相反我能够获取使用xpath的值：a / aff / @ value。

但我无法找回价值，请你帮助我？

<?xml version="1.0" encoding="UTF-8" ?>
<a>
   <aff xml:id="af1" value="a">
        <uAff>
            Hello
        </uAff>
    </aff>
    <aff xml:id="corr1">
        <uAff>
            Hello1
        </uAff>
    </aff>
</a>

To get the value of the attributes you could use:

要获取可以使用的属性的值：

/a/aff/@*[name()='xml:id']

#2

/a/aff/@xml:id works just fine in getting the values...

/ a / aff / @ xml：id在获取值时效果很好......

Are you trying to get both values?

你想要获得两个价值观吗？

If you are trying to get just the first value you could use /a/aff[1]/@xml:id

如果你想获得第一个值，你可以使用/ a / aff [1] / @ xml：id
