[MarkLogic Dev General] Any help for passing a value from XSLTForms to XQuery?

Mon Jun 14 13:59:22 PDT 2010

Is anyone using XSLTForms and passing data from the form to a XQuery
module?

If so, what are the XLSTForms structures that you use to accomplish this
task?

Subject: [MarkLogic Dev General] using input from XForm "input" in
xquery

Ok, I'm not well versed in HTML, Javascript, CSS, etc., so I thought I'd
try XForms.

I am not getting how to use the "input" I get from a user and "pass"
that string of text to an XQuery, then use the result of an XQuery as
the "output" in the XForm.

Scenario:

User enters a string of text.

User clicks button 

                [clicking button passes string to xquery function that
returns modified string of text]

User sees the modified string of text.

I have looked at many of the basic examples for XForms but I'm just not
seeing how to incorporate XQuery the way I'd like to...

Here's essentially what I want to do [with the "problem" highlighted in
yellow]:

xquery version "1.0-ml";

import module namespace nrmq = "/norm" at "/norm/normalizeQuery.xqy";

xdmp:set-response-content-type("application/xml"),

<?xml-stylesheet href="xsltforms/xsltforms.xsl" type="text/xsl"?>,

<?xsltforms-options debug="yes"?>,

<html xmlns="http://www.w3.org/1999/xhtml"

xmlns:ev="http://www.w3.org/2001/xml-events"

xmlns:xf="http://www.w3.org/2002/xforms">

   <head>

      <title>The Title</title>

      <xf:model>

         <xf:instance>

            <data xmlns="">

               <QueryField/>

               <NormalizedQuery/>

            </data>

      </xf:model>

   </head>

   <body>

      <p>Type in your query </p>   

                                                 <xf:input
ref="QueryField" incremental="true">

<xf:label>Your query: </xf:label>

                                                 </xf:input>

                                                 <p/>

                                                 <xf:output
value="QueryField">

<xf:label>As you typed it in: </xf:label>

                                                 </xf:output>

      <p/>

      <xf:trigger>

          <xf:label>Normalize</xf:label>

          <xf:hint>Hit this button when you're satisfied you've entered
your query correctly.</xf:hint>

          <xf:action ev:event="DOMActivate">

              <xf:setvalue ref="/data/NormalizedQuery">

{nrmq:normalizeQuery(/data/QueryField)}

              </xf:setvalue>

          </xf:action>

      </xf:trigger>

                         <p/>

                                                 <xf:output
ref="NormalizedQuery">

<xf:label>After it has been normalized: </xf:label>

                                                 </xf:output>

   </body>
