Example: Iterate over the children using a predicate and a triple
In this example, we iterate over a predicate instead of the children of a container. Rather than using the containment attribute, here we just use a <triple>.
<vbox datasources="animals.rdf" ref="http://www.some-fictitious-zoo.com/humans/robert">
<template>
<rule>
<conditions>
<content uri="?uri"/>
<triple subject="?uri"
predicate="http://www.some-fictitious-zoo.com/rdf#favoriteAnimal"
object="?child"/>
<triple subject="?child"
predicate="http://www.some-fictitious-zoo.com/rdf#name"
object="?name"/>
</conditions>
<action>
<label uri="?child" value="?name"/>
</action>
</rule>
</template>
</vbox>
