change namespace using XSLT

[harrazh]

He Guys,
I'm new to the XSLT , so u might find my question very stupid, but please bare with me

I have a soap request with a namespace to qualify the function required, I need to change the namespace so that the webservice won't reject it, please see below

the request will look like the following example
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:q0="http://address.com" >
<soapenv:Body>
<q0:findByLocation>
<city></city>
<state>NC</state>
</q0:findByLocation>
</soapenv:Body>
</soapenv:Envelope>

I want it to be transformed into

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:q0="http://east.address.com" >
<soapenv:Body>
<q0:findByLocation>
<city></city>
<state>NC</state>
</q0:findByLocation>
</soapenv:Body>
</soapenv:Envelope>

I only need to change the q0 namespace
how can I do that?

another thing, I need a book name or a good reference to teach me XSL transformation
