Subject: Getting rid of empty namespaces in the result

Hi

I'm using a Saxon XQ transform, of a message as follows, that contains a bunch of SOAP envelopes within an element "root"

<root>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:getQuoteResponse xmlns:ns2="http://soap.services.samples/">
<return>
<last>4.386254124908056</last>
....
</return>
<ns2:getQuoteResponse>
</S:Body>
</S:Envelope>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:getQuoteResponse xmlns:ns2="http://soap.services.samples/">
<return>
<last>4.386254124908056</last>
....
</return>
<ns2:getQuoteResponse>
</S:Body>
</S:Envelope>
...
</root>

I want to select the SOAP envelope with the lowest <last> price value, and my XQ is as follows:

xquery version "1.0";
declare namespace s="http://schemas.xmlsoap.org/soap/envelope/";
declare namespace ns2="http://soap.services.samples/";
declare default element namespace "";
let $envs := .//s:Envelope
let $min := $envs[s:Body/ns2:getQuoteResponse/return/last = min($envs/s:Body/ns2:getQuoteResponse/return/last)]
return $min

This gives me the result I desire.. but with empty namespace elements as follows:

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/" xmlns="">
<S:Body xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<ns2:getQuoteResponse xmlns:ns2="http://soap.services.samples/">
<return xmlns="">
<last xmlns="">-2.3526707402807023</change>
...

When what I require is the above result without the 'xmlns=""' parts

Any help is greatly appreciated
thanks
