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
