Title: Access content of an Artifact (Internal) with scripts
Post by: Daiim on May 02, 2022, 04:50:38 am

Hi everyone,

I try to access an embedded file (internal artifact) from code to read it's content. But sadly I can not find an approach how to do this.
The EA.Element has an property "IsInternalDocArtifact" but this is 'false' for my element. I also tried to access the "MiscData(0..)" property but got nothing.
The first approach was to acces the Files collection of the element but this is empty, too.

A workaround is to add it's content to a linked document but that seems to be confusing, as the file is opened via double click on the diagram element, so the data must be somewhere.

Any ideas?

Daniel

It's in t_document linked via ElementID. The binContent holds the zip with a single file str.dat. repository.sqlquery will return  that as base64 encoded data.

Not sure whether the API meanwhile offers more comfort. I guess not. There are a couple of threads here that detail the procedure. Try looking for "str.dat" or anything else mentioned above.

Thank you for this hint. This is a good point to start but it seems to be quite tough to implement with jscript, so I'll use the workaround for the first shot. Maybe I can find some time to figure out how to directly access the content with jscript later.

Can't speak for that J-stuff but it's not rocket science. So there should be libs to deal with base64 as well as zip files. Good luck anyway.

Is there a way to load external libraries from inside EA scripting environment?

I hope I'm not late for the party, but there is a solution using the decodeBase64zippedXML() function of the Geert's framework (https://github.com/GeertBellekens/Enterprise-Architect-VBScript-Library/tree/master (https://github.com/GeertBellekens/Enterprise-Architect-VBScript-Library/tree/master)). In the example below I'm using another lib for parsing a JSON stored as a content of the artifact element. (For the JSONClass see https://gist.github.com/t3rminus/d278175893dea1ecfed83c29df56a9d8#file-vbsjson-vb (https://gist.github.com/t3rminus/d278175893dea1ecfed83c29df56a9d8#file-vbsjson-vb)).

Code: [Select]

option explicit

!INC Local Scripts.EAConstants-VBScript
!INC Tools.JSONClass
!INC Utils.Include

sub main

' get the content from DB
dim sql
sql = "select BinContent from t_document where DocName = 'data.json'"
dim result
result = Repository.SQLQuery(sql)

dim JSON, configJSON, config
' b64 decode and unzip
configJSON = decodeBase64zippedXML(result, "BinContent")

set JSON = new vbsJSON
' decode JSON
set config = JSON.decode(configJSON)

' use the data
        ' ...
end sub

main


(I've spent some time trying to find the solution, so I hope this might help someone.)
