Using <xf:copy ref=".">  instead of <xf:value ref="@id">?

Ah, clever! (I have a lot to learn ...)

Thank you: I can now get the text content of all the selected XML records 
dumped out as a long unformatted string, using <xf:output 
ref="Object/ItemList">. 


I see I can use the value attribute on <xf:output> to evaluate a single 
XPath expression, but is there a way of iterating over the nodeset of 
selected Object elements and just outputting selected elements, ideally 
with some formatting? 

That's what <repeat ref="..."> is for.


I have written an XForms hands-on tutorial, available at 
https://cwi.nl/~steven/xforms/xforms-hands-on/ which introduces many of 
these techniques, and I will be giving a follow-on advanced XForms hands-on 
at the Declarative Amsterdam conference on  November 1st (online and live).

Hi,

When I make a selection from a number of options:

       <xf:select bind="object-list" appearance="full">
          <xf:label>Objects to move:</xf:label>
          <xf:itemset model="objects-chosen" 
nodeset="instance('objects')/record">
             <xf:label ref="Object/ObjectIdentity/Number"/>
             <xf:value ref="@id"/>
          </xf:itemset>
       </xf:select>

The <object-list> in my model is dynamically populated with a 
space-separated list of id's.

What I would like to be able to do is to display (elsewhere on the XForm) 
selected information for each of the objects which is currently selected.  
I can (and currently do) display all the objects, e.g.:

       <h4>Object details:</h4>
       <div>
          <p><b><xf:output 
ref="instance('objects')/record[1]/Object/ObjectIdentity/Number"/></b>
          <br/><b>Identification: </b> <xf:output 
ref="instance('objects')/record[1]/Object/Identification/ObjectName/Keyword"/>;
          
<xf:output 
ref="instance('objects')/record[1]/Object/Identification/BriefDescription"/></p>
       
</div>

Is there a way of iterating over the selected objects and outputting only 
their details?

Thanks,

Richard
