bind a control to an element's attribute?

Hello,

Is it possible to bind a control to the *attribute* of an element in the model?

<xf:model>
        <xf:instance xmlns="">
            <foo>
                  <bar attr="something">
            </foo>
        </xf:instance>
[...]
</xf:model>

<body>
    <xf:input ref="bar@code">
       <xf:label>value</xf:label>
   </xf:input>
</body>

The reason for this unusual request is that, ideally, the XML captured via XForm would be as the one used by our application and which, for some fields, uses attributes not elements. I tried <xf:input ref="bar@code"> and <xf:input ref="bar[@code]"> but they don't work.

Is there an elegant solution for the above case? An obvious one is to collect the information in subelements and then, before the final processing for our application, convert certain subelements into attributes. Yet perhaps there is a better way, hence the question. In our case, forms are definable by users, so having fancy event processing would be way too much for them.

Thanks,
JL

JL,

Yes. This is a very common thing to do. Your syntax needs to be changed. This should clear things up:

the attribute name you show is actually ‘attr’
the syntax to reference the attribute should be (you need the slash) <xf:input ref="bar/@attr">

Re: bind a control to an element's attribute?

Thanks Michael and Alexander, it works fine now with the / (the "code" instead of "attr" was a copy & paste error).
