New XSLT 2.1 feature? :)


Could be something as:

      keys(keyname as xs:string) as item()*

and an additional overload:

      keys(keyname as xs:string, document as document-node()) as item()*

Hi List.
I would like to know if it is possible to get all "key" item from an
xsl:key ?
I mean:
when you define a key, say:
      <xsl:key name="mykey" match="NODE" use="@id"/>

You can retrieve all NODE nodes with a given @id attribute.
But is it possible to retrieve all distinct @id values from the key ?
(I know it is possible to get them from the XML file, but wouldn't it be
faster to get what is already retrieved ?)


No, this isn't available. I don't think there's any good reason for not
providing it.
