Extract InstanceSlots from Rhapsody with RPE

0
Calum Button (13●12) | asked Feb 14 '22, 11:32 a.m.

 Hi,


I am beginning to use RPE with Rhapsody and can mostly navigate the schema to extract some Rhapsody elements.  However, I am now stuck and am looking for some help.

Would anyone be able to offer advice on how to extract the information contained in an InstanceSlot?  At the moment I have used NestedElements but simply get InstanceSlot 0 etc. rather than the name and values of the element associated with the InstanceSlot.

Apologies if the question is a bit garbled.

Many thanks in advance

Calum

Hello
I have:
Block A with Value Properties X
InstanceSpecification a:A with InstanceSlots X = "abc"

I can extract the InstanceSlots Name with
Projects/Project/
  Packages/Package/
    InstanceSpecifications/InstanceSpecification   ( name is  a)
      instanceSlots/InstanceSlot  ( name is  instanceslot_0)
        SlotProperty/ModelElement
          name ( will return 'X' )

According to the return XML from the query the Instance slot value "abc" should be here:
InstanceSpecifications/InstanceSpecification/instanceSlots/instanceSlot/Values/ValueSpecification/value

But the Rhapsody PUB Schema do not contain the trailing "value" element
I will keep looking into it.

Thanks Pierre,

I tihnk that's where I am, but I'm trying some other cast to types having read your answer - I'm sure it can be done...

I still cannot access the "value" element.
I believe it is a defect and have opened a support case.
I will  update you when I have news.

  My library won't load. I recently updated my windows 10 and it seems to have broken something such as my discord.
