I notice Basex has a util:eval function similar to the eXist db onehttp://demo.exist-db.org/exist/functions/util/evalhowever it is not clear for the BaseX version what the inherited context, if any, is. The example on the eXist site:
let $a := "Hello" return util:eval("$a")
Fails with an undefined variable $a with BaseX 7.0.1

Hi Andy,
as you already guessed, and to reduce side effects, the util:eval() function in BaseX uses its very own context.
Hope this helps, Christian _______________________________________

Ok, I understand, but a bit of a shame. The functionality I want is just functx:dynamic-path http://www.xqueryfunctions.com/xq/functx_dynamic-path.html Is just using the functx library via the repo likely to be the most efficient approach for BaseX?

Hi Andy,
it sure is the most comfortable approach, I myself use the functx library via our repository extension.
REPO INSTALL http://files.basex.org/xar/functx-1.0.xar
Hope this helps :-)

You can even find it directly from CXAN ;-)
There seems to be a namespace issue when using nested modules... This works..
import module namespace functx="http://www.functx.com"; functx:capitalize-first("test")
I define foo.xy..
module namespace foo = "http://example.org/module1"; import module namespace functx="http://www.functx.com"; declare function foo:first($s){ functx:capitalize-first($s) };
Then execute import module namespace foo = "http://example.org/module1" at "foo.xq"; foo:first("aa")
I get the error Query: import module namespace foo = "http://example.org/module1" at "foo.xq";
foo:first("aa") Error: [FONS0004] Namespace prefix not declared: "functx:Different_number_of_names".
This works: import module namespace foo = "http://example.org/module1" at "foo.xq"; declare namespace functx="http://www.functx.com"; foo:first("aa")
But surely I should not be required to define the functx namespace here?

Thanks Andy,
this problem seems to be related with GitHib issue 133..
https://github.com/BaseXdb/basex/issues/133
..which is why I have added your observation to this bug entry.
