Local schemas and selecting paths

[Anthony Ikeda]

I'm new to XQuery and trying to get the hang of it and so far so good.

 

One question I have is selecting XPaths using a locally declared
namespace. For example I have the following XQuery:

 

declare namespace a = "myNamespace.xsd"

 

<result>

            {

for $val in /a:trains/a:types

return $val/text()

}

</result>

 

Both the xquery document and the schema exist in the same folder side by
side.

 

Typically I've declared namespaces using URIs rather than locally but
find that I do not get a result from the above code (The same goes when
I use the file:// protocol in the namespace declaration).

 

If I use the fully qualified path (I think that's what it's called) like
so:

 

<result>

            {

for $val in /*[name="trains"]/*[name="types"]

return $val/text()

}

</result>

 

Then there is no problem.

 

I've tried running the above xqueries using the Stylus Studio built in
engine and the Saxon query engine (v7) also in Stylus Studio.

 

Does anyone know where I'm going wrong?
