[Xsltforms-support] Accessing the results of a multi-select

From: Richard L. <ric...@gm...> - 2023-09-28 10:40:32

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

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?

Thanks,

Richard

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).
