Python API is not able to generate a model for parsing xbrl

[Anand Singh]

Hi Team,  thanks for the Arelle python package, it is amazing. I am however stuck on one thing. I am not able to read an xbrl file for Indian company.

runtime_options = RuntimeOptions(

entrypointFile=file_path, #My xbrl file from NSE Website

validate=False,

packageManifestName='/Users/xxxxhome/Taxonomy Integrated filing finance (IndAS)/META-INF/taxonomyPackage.xml', # https://nsearchives.nseindia.com/web/sites/default/files/inline-files/Taxonomy%20Integrated%20filing%20finance%20%28IndAS%29.zip

logFile='logToBuffer', # Capture logs in memory.

logFormat="[%(messageCode)s] %(message)s",

disablePersistentConfig=True

)

try:

with Session() as session:

session.run(runtime_options)

models = session.get_models()

model_xbrl = models[0] # Get the primary loaded model

Error: Arelle session did not produce a model for /Users/xxxhome/filings/3MINDIA/Integrated Filings/INTEGRATED_FILING_INDAS_1455634_28052025092643_WEB.xml. Check logs for errors.

No data could be parsed from the file. Exiting.

Can someone please help me on this, I will be very grateful.

Thanks

Hi Anand,

"Arelle session did not produce a model" does not appear to be an error message that Arelle generates, nor do I see it in your code.

Would you be able to provide the full log output as well as any additional code for context?

Thanks,

Aaron

Actually, I just encountered this same issue while working on something else. I think adding `keepOpen=True` to the RuntimeOptions will give you the results you're looking for. 

It might make sense for us to make this a default value for the Session API. I'll bring it up for discussion with the team.

Thanks so much Aaron, I was missing the Keep Open tag.

Also another problem I face is that Arelle I am giving the taxonomy zip file which has all the roles, ref end def, cal, pre files and META-INF and Core folders separately. But still it is expecting the xsd file in the home directory where my instance file is saved. How can I direct Arelled to look for instance file in the Taxonomy zip.

Kindly help. Thanks so much in advance
