v3.0.0 - Fails to extract facts for Older FIlings

[rj3185]

XBRL document
The issue is observed with multiple older filings, as an example please look at 0001104659-23-073356 Also, while iterating consider it as an inline XBRL .. hence reference .. filing/0001104659-23-073356\\vod-20230331x20f_htm.xml

Describe the bug
This process fails at the line highlighted ..

with the error
` root: ET.Element | None = parse_file(instance_path).getroot()
if root is None:
raise InstanceParseException("Could not parse instance file!")
# get the link to the taxonomy schema and parse it
schema_ref: ET.Element | None = root.find(LINK_NS + "schemaRef")
if schema_ref is None:

      raise InstanceParseException("Document does not import any taxonomy schema")

E xbrl.InstanceParseException: Document does not import any taxonomy schema`

@manusimidt - Please look into this issue :) Thanks so much

Hi,

unfortunately the XBRL file is just invalid, since it has no schemaRef.

According to XBRL Specification, every XBRL document must have a schemaRef defined, without it, there is no way of parsing the document.

So the parser is correctly throwing a xbrl.InstanceParseException.

Interestingly the iXBRL version works without issues. I would anyways always recommend iXBRL over XBRL. Since 2018 the SEC also requires all filers to use iXBRL, not XBRL.

@manusimidt - Thanks for the information .. let me check and get back to you .. Can we keep this ticket open .. for at least one more week ? The ONLY reason .. is that we are presented the filing by PDS as a "dissem" so .. I would like to look at our code and figure.. what are we doing here ..
