How to open and iterate submodels from AASX file? about basyx-python-sdk

[jkhsjdhjs]

Are you by chance using the v2.0.1 branch of this SDK? Please make sure you're using either the latest release or the main branch of the basyx-python-sdk.
In case you're already using the latest version can you share the AASX you're trying to read with us?

I was using an older version of the library, I installed now from the main branch, thanks!
However, now I get a different error - aasx-origin Relationship missing.
The file that I try to open is from the online available aasx files (27_Festo.aasx)

That's a bug in the AASX file. While it does contain relationship files, _rels/.rels, aasx/_rels/aasx-origin.rels, etc., these files are just empty so the AASX reader cannot determine which file to load the AAS data from. But even if the relationship files weren't empty, you still wouldn't be able to read anything from it as the only XML file (aasx/http___smart_festo_com_aas_99920200616193249000010710/http___smart_festo_com_aas_99920200616193249000010710.aas.xml) is also empty. This AASX package doesn't contain any asset administration shell data, only PDF, PNG and ZIP files.

BTW did you use a different AASX file when you first reported this issue with the older SDK version?

I tried also with the 36_Murrelektronik.aasx file and I got the same issue with the older version, but also with the new version. This file contains relationship files (aasx/AssetAdministrationShell---10A74E49/_rels/AssetAdministrationShell---10A74E49.aas.xml.rels), and this file is not empty.

This is the page from where I downloaded these files.

I also have some local .aasx files that I am trying to open but I get the same errors as with the Festo and Murrelektronik file.

I just tried opening 36_Murrelektronik.aasx with the v2.0.1 branch of the basyx-python-sdk and got a lot of warnings because the file isn't entirely compliant to the specification, but was able to read most data from it.

I'll close this issue now. Feel free to reopen, if you have any further questions.
