Darin; There are some problems with the ApplyConstruct query that
could be causing the problem. An instance of the <attribute> element
is created, but is then is declared to be the composite:child of a
bnode (_:b0). But since the bnode is not linked to any XML
structures, this will not appear in the XML document. Instead, for
each match in IterateOverSelect, the <attribute> element is set as a
composite:child of CQ:Documentr-3-3, which I take to be the
<attributes> tag. If the match to ?rStringAttributeNodeName resolved
to the same uri, then all will be placed in the same <attribute>
element. I suspect this is what is placing all of your data in the
one tag (it's hard to say without knowing what the data is).
The bnode _:b1 will not be added to the XML file, as it is not linked
to the XML structure. If the intent is to create multiple <attribute>
tags, one for each match in IterateOverSelect, then something like the
following should get you what you need:
CONSTRUCT
{ _:b0 :qualifier-attribute "MashupData" .
_:b0 :type-attribute ?stringPredicate .
_:b0 composite:index 0 .
_:b0 a :attribute .
CQ:Documentr-3-3 composite:child _:b0 .
}
Again, I am assuming that CQ:Documentr-3-3 is the <attributes> tag.
(Using the named uri, ?rStringAttributeNodeName, instead of the bnode
_:b0 is also acceptable, as long as ?rStringAttributeNodeName creates
unique names.)
