[basex-talk] using variables along with namespace prefix

Hi,

I am using the sample xml document(xyz) shown below:

<entry xmlns:libx="http://libx.org/xml/libx2"> libx:libapp First libapp </libx:libapp> libx:libapp Second libapp </libx:libapp> </entry>

I am using BaseX 6.5.2 and am trying to use a variable along with a namespace prefix in my sample xquery like so:

declare variable $libx_ns as xs:string external; declare namespace libx=$libx_ns;

let $type := 'libapp' return doc('xyz')/entry*[libx:{$type}]*[1]

When I pass the value "http://libx.org/xml/libx2" to the parameter libx_ns and run the above xquery I see the following exception: [XPST0003] Incomplete expression.

However, the following xquery works:

declare variable $libx_ns as xs:string external; declare namespace libx=$libx_ns;

let $type := 'libapp' return doc('xyz')/entry*[libx:libapp]*[1]

The child nodes could be libx:libapp or libx:module etc. So, I will have to use a variable rather than hard wiring the actual child name. But, I am not sure how to use a variable along with a namespace prefix. Am I doing something wrong or is this a bug ?

Thanks, Sony
