Hello,

I noticed that the order of my FLWOR expression is not kept when I do an xpath on the node list:

> basex 'declare function local:nodes() {let $data := (<test a="2"/>, <test a="1"/>) let $nodes := trace(for $n in $data order by xs:integer($n/@a/data()) return $n) return $nodes }; local:nodes()/@a/data()'

<test a="1"/>

<test a="2"/>

I would expect it to return it in order.

Is it a bug or or some optimization allowed by XQuery?

I tried it on the latest snapshot (BaseX90-20171020.102055.zip).

Best regards,

Iwan
