Hasan,

There is a service editor and an action editor which allow you to do this from Form Builder directly (although 3.7.1 is very old now, so I don't know the status of these editors in the version you are using).

Barring that, as Hank suggests, you can write custom XForms in the form to run a submission to load the data into an instance, and manually modify the select control's itemset to point to that instance.

Hi Hasan,

You can use the src attribute to have the instance loaded :

<xforms:instance id="stations"
src="<a href="http://db.nees.ucsb.edu/exist/rest/db?_query=doc('/pub/stations.xml')" target="_blank">http://db.nees.ucsb.edu/exist/rest/db?_query=doc('/pub/stations.xml')"/>

The select control has an itemset with a nodeset attribute. Sorry that the
xpath and all looks complicated. Note that you can have both items and itemsets,
so you can have a "slect one" etc. :

<xforms:select1 ref="sta" id="sta-select">
<xforms:item>
<xforms:value/>
<xforms:label> Select Station ... </xforms:label>
</xforms:item>
<xforms:itemset nodeset="instance('stations')//pfarr[@name='Sta_Info']/pfarr">
<xforms:value value="upper-case(@name)"/>
<xforms:label><xforms:output value="concat(upper-case(@name),' - ',pfstring[@name='Description'])"/></xforms:label>
</xforms:itemset>
</xforms:select1>

<xforms:itemset nodeset="instance('stations')//pfarr[@name='Sta_Info']/pfarr">
<xforms:value value="upper-case(@name)"/>
<xforms:label><xforms:output value="concat(upper-case(@name),' - ',pfstring[@name='Description'])"/></xforms:label>
</xforms:itemset>

HTH,
Hank
