The XML representation of multiple reference attributes is as a sequence of reference elements – each one including also the sub-attributes (if any); e.g. something like this:

 <gn4:story id="obj41196">

   . . .

  <gn4:objs nav:handle="1">

      <gn4:ref idref="obj41197">

        <gn4:title>Sub title</gn4:title>

        <gn4:caption>Sub caption</gn4:caption>

        <nav:refObject idref="obj41197">

          <gn4:image id="obj41197" . . .>

          </gn4:image>

        </nav:refObject>

      </gn4:ref>

      . . .

    </gn4:objs>

   . . .

 </gn4:story>

for the assets associated with a story via the ‘objs’ multiple reference attribute. Based on this representation, the query to find all the stories associated with the object with database id 41197 is

 gn4:story[gn4:objs/gn4:ref/@idref='obj41197']

The query to find all the stories associated with an image titled ‘Test’ is:

 gn4:story[gn4:objs/gn4:ref/nav:refObject/gn4:image/gn4:title='Test']

Sub-attributes can be used as well, so

 gn4:story[gn4:objs/gn4:ref/gn4:caption='Sub caption']

returns all stories with an associated object caption ‘Sub caption’. Conditions on sub-attributes and referenced objects can be combined of course, for example

 gn4:story[gn4:objs/gn4:ref[@idref='obj41197' and contains(gn4:caption,'Israel')]]

returns all stories associated with the object with database id 41197 with a caption containing the word ‘Israel’. Note that this is not the same thing as

 gn4:story[gn4:objs/gn4:ref/@idref='obj41197' and

   contains(gn4:objs/gn4:ref/gn4:caption,'Israel')]

that returns all stories that are associated object with database id 41197 and that also have an associated object (not necessarily the same one) with a caption containing the word ‘Israel’.

The same ‘nav:referencing’ representation is available for multiple reference objects, so the query

 gn4:image[nav:referencing/nav:referencingBy[@attrName='story.objs']

   /nav:refs/nav:refObject]

returns all images associated to at least one story, and

 gn4:image[nav:referencing/nav:referencingBy[@attrName='story.objs']

   /nav:refs/nav:refObject/@idref = 'obj41196']

returns all images associated with the story with database id 41196.
