Question

I created a form using Orbeon form builder, and i included in its form instance the content of an xml file using :

<xi:include href="oxf:/path/file.xml" xxi:omit-xml-base="true" />  

When i save the form in form builder and edit it, i get a new form, and when i publish it and run it in form runner i get a blank page.

Can you tell me please what’s wrong with the xi:include ?

1. If you want to include the whole content of an external file as the instance, use:

   <xforms:instance id="main-model-instance" src="oxf:/path/file.xml"/>
   

   Here we have the model instance xml in external file at /path/file.xml and we are using this file into our form and have named the model instance as id="main-model-instance"

2. If you need to add part of the instance from external file, then insert that piece dynamically during xforms-model-construct-done event, e.g.:

   <xforms:action ev:event="xforms-model-construct-done">
       <!-- Extracts the element some-section from file.xml and uses it as the 
            root element of the fr-form-instance -->
       <xforms:insert context="instance('fr-form-instance')"
            origin="doc('oxf:/path/file.xml')/root-element/some-section" />
   </xforms:action>
