xquery via exist REST Api examples&doc.

would you please give me any insight about this?

i've been encouraged by you to use REST Api over xmldb processors (see http://www.orbeon.com/ops/doc/processors-xmldb introduction note), but I have not found any example of how can one do this, I've managed to build one working example but I'm not able to get what I want (showed below return a list of collection names ang aggregate them using a container node).

    <p:processor name="oxf:xslt">
    <p:input name="data" href="#instance"/>
    <p:input name="config">
        <exist:query xmlns:exist="http://exist.sourceforge.net/NS/exist" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xsl:version="2.0">
        <exist:text>
            xquery version "1.0";
            declare namespace xmldb="http://exist-db.org/xquery/xmldb";
            let $collection-name := '/db/orbeon/neuro/<xsl:value-of select="/parametros/id_hospital"/>/'
           
 Offending line>>>   <expedientes>
                for $resource-name in xmldb:get-child-collections($collection-name)
                    return $resource-name
 Offending line>>>   </expedientes>
           
        </exist:text>
        </exist:query>
    </p:input>
    <p:output name="data" id="consulta"/>
    </p:processor>

    <!-- Ejecutar el REST submission -->
    <p:processor name="oxf:xforms-submission">
        <p:input name="submission">
            <xforms:submission xmlns:xforms="http://www.w3.org/2002/xforms"
                 method="post" action="/exist/rest/db/orbeon/neuro/"/>
        </p:input>
        <p:input name="request" href="#consulta"/>
        <p:output name="response" debug="consultaExpedientes" ref="data"/>
    </p:processor>

This example works if I drop away the offending lines..

thx a lot

Richard,

The issue I think is that <exist:text> expects a query in plain text,  
that is with no nested elements. So try changing:

   <expedientes>

to:

   &lt;expedientes>

oooops. I see no difference!

going to share the findings researching about this stuff.
I've used the eXist query client against the orbeon exist
servlet withi this:

let $collection-name := '/db/orbeon/neuro/demo/'
for $resource-name in
xmldb:get-child-collections($collection-name)
                order by $resource-name
                return
                <expediente numero="{$resource-name}">
{
                        for $valoracion in
xmldb:get-child-resources(fn:concat($collection-name,$resource-name
,'/escalas/barthel/'))
                        let $valoracion-actual :=
fn:doc(fn:concat($collection-name,$resource-name,'/escalas/barthel/'
,$valoracion))/cuestionario-relleno
                        return $valoracion-actual/fecha
}
                </expediente>

and it throws a correct result like this:

<expediente numero="1">
    <fecha>2008-11-13</fecha>
    <fecha>2008-10-01</fecha>
</expediente>
<expediente numero="87978">
    <fecha>2008-10-01</fecha>
    <fecha>2008-11-08</fecha>
    <fecha>2008-12-07</fecha>
    <fecha>2009-01-02</fecha>
    <fecha>2009-02-08</fecha>
    <fecha>2009-03-06</fecha>
</expediente>

using this query as text for the rest submitting, i've first
got a 2008-11-19 18:43:10,115 DEBUG XFormsServer  - XForms -

Mmh, broken client, either on my side your your side (and/or broken  
Nabble?). The difference is was trying to express was that you should  
escape the opening brackets. Instead of writing a literal "<", write  
"ampersand-lt-semicolon".
