XQuery did not find the right child nodes.

Running the “similar” Xquery and Xquery (see bellow), searching for the same word, the results don’t match the same nodes, it return only the first artigo-texto (child node) of artigo element (parent).

I will use this Xquery to formulate a more complex one. (Ex. to get other elements)

Is it a wrong Xquery?
Is the problem in the Schema?

The attached file contain the Tamino Schema and XML DataLoader File.


The XQuery:

declare namespace tf=“http://namespaces.softwareag.com/tamino/TaminoFunction”
declare namespace ino=“http://namespaces.softwareag.com/tamino/response2”
for $a in input()/norma//artigo-texto
where tf:containsText($a, “fundamental”)
return { $a }

Results:

<?xml version="1.0" encoding="windows-1252" ?>

Stuart (Software AG - UK) sent the following tip to me. I think it could be useful in other queries that use text retrieval; it runs fine, see the result bellow.

Thanks.

The following query should do the trick:-

declare namespace ino=“http://namespaces.softwareag.com/tamino/response2”
for $a in input()/norma//artigo-texto
let $b := {$a}
where tf:containsText($b,“fundamental”)
return
{$b/*}

By creating separate elements to contain each arigto-texto element and then using containsText() function againest each of those elements solves the problem. I have no idea why this makes a difference and hopefully a developer will be able to explain. But I suspect it relates to the way containsText() works.
