How to retrieve value of an attribute which contains colon in the attribute name using xpath

问题

I have a simple requirement where in I need to fetch the value of attribute xml:id i.e af1. I am making use of a SAXParser and here is my xpath:a/aff/@xml:id on the contrary I was able to fetch value of using the xpath:a/aff/@value.

But i was unable to retrieve the value could you please help me?

<?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>

Thanks in advance.

回答1:

To get the value of the attributes you could use:

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

回答2:

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

Are you trying to get both values?

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