DNG: How to get number of artifacts(count) under shared view selection

Dear Community,

I am working on developing a Java based application which help us to get number of artifacts(count) when we select any shared view.

For reference you can also reference the attached screenshot.

Also i did tried hitting this api in rest client but ended up getting this response (Source : https://jazz.net/wiki/bin/view/Main/RRCReportableRestAPI)

API(GET) :

https://host/rm/publish/resources?viewName=View_CRS_Reqs_all&projectURI=_AE4pALUfEe6Ul8nmauCi8Q&moduleUri=MD_dvPjobUgEe6Ul8nmauCi8Q

Headers :

vvc.configuration: https://host/rm/cm/stream/_Aaa0JrUfEe6Ul8nmauCi8Q

Accept: application/xml

Please note our RM project is not full configuration management enabled,

In response file you can see that there is no where mentioned total count as 5 , there is something like rrm:totalCount="21" but i don't know what is that

Sorry I cannot upload response as it contains company data, but by referring attached image I believe you got what exactly I am looking for

 DNG Version : 7.0.2, ifix027

Thank you
