2022-01-10 00:00:00 xml xml-parsing android java saxparser

我有一个简单的要求，我需要获取属性 xml:id 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 的值xpath:a/aff/@value.

<?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>
