Dear all,

could you please give me a short hint on these questions ?

1) where to find documentation and source code for the "Data"-function for
JEXL evaluator ? I need to clarify which subset of XPath is supported.

2) there is no "name" attribute on <data> in current working draft, but
Data() depends on it:

a) <data ID="foo"><foo>bar</foo></data> b) <data name="foo"><foo>bar</foo></data>

the action <log expr="Data(foo,'node()')"/>

- throws an error for a: Data(): Cannot evaluate an XPath expression in the
absence of a context Node - returns "bar" for b)

Will the Data() implementation be adapted to the spec ?

3) How to address nodes in a specific namespace via Data() ?

<data name="foo"><f:foo xmlns:f="fooNS"><baz>bar</baz></f:foo></data> <!-- how to address f:foo ? --> <log expr="Data(foo,'foo')"/>

4) assign supports static source-URLs via @src. Is there a way to supply an
srcexpr, or what would be the recommended way to perform and store XML data from
parametrized GET-requests ?

broken example:

<data ID="MyId">3q495</data> <assign location="Data(test,'response')" expr="
'http://localhost:8080/exist/ess/queries/getData.xqy?id=' + MyId "/>

Many thanks ! Jaro
