Subject: Xquery outputs XML attributes sorted by attribute name

Is there a setting or reason when using attributes in xquery the xml output displays the attributes in ascending order?

Sample xquery code snippet;
<Test>
{
for $Record3 at $i in doc('file:///c:/userfield.xml')/Records/Record
where (($Record3/batch_number = $Record2/batch_number) and ($Record3/tran_number = $TranNo)) and ($Record3/docformat_id = $Record5/docformat_id)
return
<TtestField test6="test6" test4="test4" test7="test7"/>
}
</Test>

When the code is executed the following is output;
<Test>
<TestField test4="test4" test6="test6" test7="test7"/>
</Test>

Notice the order in which the attribute displays has changed from what is written in the code? In code it is test6, test4, test7. The output sorts the attributes; test4, test6, test7. I've hardcoded the values in the sample but using actually data "{$datafield} presents the same issue.

Thanks.

What XQuery processor are you using? I don't see that behavior using DataDirect XQuery, but I do see it using Saxon.

BTW, the order of attributes is completely irrelevant in the XML InfoSet... so, what you are describing is just an entirely legitimate serialization choice.

I've tried using the built-in and saxon processor. Is there a way to turn it off?

"it" being? The ordering of attributes? Not that I know of; you may want to ask saxonica dot com about Saxon.

As I said, DataDirect XQuery doesn't seem to re-order them in the cases I checked; DataDirect XQuery is bundled with all Stylus Studio Enterprise Suites.
