BaseX team,

Sorry for the long question but I just figured out what is going on...

The '$stereotypes' is a gigantic sequence, which is why I can't separate its members into sequences.

Hope you guys have a great week,

Hello BaseX Staff,

I am trying to access members of a sequence that I have created already, but it whenever I use the functions subsequence() it returns the entire sequence, and count() always returns 1.

The code:

xquery version "3.1";

declare namespace map="http://www.w3.org/2005/xpath-functions/map";

declare namespace xmi="http://www.omg.org/spec/XMI/20131001";

declare namespace uml="http://www.omg.org/spec/UML/20131001";

declare namespace MagicDraw_Profile="http://www.omg.org/spec/UML/20131001/MagicDrawProfile";

declare namespace Extra_stereotypes="http://www.magicdraw.com/schemas/Extra_stereotypes.xmi";

declare namespace UAF="http://www.omg.org/spec/UPDM/20121004/UPDM-Profile";

(

  let $begin := db:open("CubeSatUML2.5XMIv3")/xmi:XMI/uml:Model/packagedElement

  let $modelContent := $begin//packagedElement[@xmi:type="uml:Class"]

  (: Combine the names of the elements with their ID's :)

  let $names := $modelContent/@name

  let $ids := $modelContent/@xmi:id

  (: Grab all stereotypes, properties:[attributes, comments] :)

  let $stereotypes := for $id in $ids

    let $stereo1 := /xmi:XMI/*[@base_Element=$id]

    let $stereo2 := /xmi:XMI/*[@base_Class=$id]

    let $attributes := $begin//*[@xmi:id=$id]/ownedAttribute/[@name | @xmi:type | @xmi:id]

    let $comments := $begin//*[@xmi:id=$id]/ownedComment/[@name | @xmi:type | @xmi:id | @body]

    let $combined := ($id, $stereo1/name(), $stereo2/name(), $comments, $attributes, "")

    return $combined

    

  let $final := 

    for $seq in $stereotypes

      return subsequence($seq, 1, 1)

(:  ^ the part in question:)

    

  return $final

  )

I realize I am creating this in a very weird way, but I want to keep the data together and have not thought of another solution.

I have tried 'for each'ing over the '$sequences' and tokenizing to get the elements out, but I get an error:

  let $finalMap := 

    for $seq in $stereotypes

      return tokenize($seq, '\s')

[XPTY0004] Item expected, sequence found: ("uml:Property", "_18_5_2_4c1014b_153850....

When I print '$stereotypes', I get what appears to be a sequence of sequences (which I don't think is a real thing, but it appears to be that)

Ex output:

xmi:id="_18_5_2_4c1014b_1538500371989_609286_80522"

UAF:ResourceArtifact

[(xmi:type="uml:Property", xmi:id="_18_5_2_4c1014b_1538500468390_289646_80939", name="flight")]

[(xmi:type="uml:Property", xmi:id="_18_5_2_4c1014b_1538500488269_847951_81240", name="ground")]

xmi:id="_18_5_2_4c1014b_1538500376501_394659_80590"

UAF:ResourceArtifact

[(xmi:type="uml:Comment", xmi:id="_18_5_2_4c1014b_1538501028725_896600_82978", body="The ground supporting equipment and operations that support the spacecraft mission.")]

[(xmi:type="uml:Property", xmi:id="_18_5_2_4c1014b_1538500492755_533021_81326", name="ground Communications")]

[(xmi:type="uml:Property", xmi:id="_18_5_2_4c1014b_1538500495333_439654_81369", name="ground Command and Control")]

[(xmi:type="uml:Port", xmi:id="_18_5_2_4c1014b_1538582001724_435913_83660", name="Flight_Ground")]

My end goal is to have a map of maps, where the root map has keys of element names (currently in $names) and the value is a map of all the properties of this element.

To do this I have to deconstruct this monster I have created, and maybe I am on the wrong path entirely but some direction would be greatly appreciated.

End goal format:

    map{

        elementName : map {

            stereotypes: map{

                stereotype_Name_1: stereotype_ID_1,

                stereotype_Name_2: stereotype_ID_2

            },

            attributeName: map{

                'id': actual_ID_here,

                'lowerValue': someValue,

                'upperValue': "*"

            },

            comment: map{

                'id': actual_ID_here,

                'xmi:type': 'uml:Comment',

                'body': actual_Comment_Here

            },

            'id': actual_ID_here

        }

    }
