parsing uk submission "KeyError: 'bus'" about py-xbrl HOT 5 CLOSED

I get the following error when parsing the submission provided by you.

  File "E:\Programming\python\xbrl_parser\xbrl\taxonomy.py", line 215, in parse_taxonomy_url
    return parse_taxonomy(schema_path, cache, schema_url)
  File "E:\Programming\python\xbrl_parser\xbrl\taxonomy.py", line 343, in parse_taxonomy
    concept: Concept = c_taxonomy.concepts[concept_id]
KeyError: 'curr_S%C3%A3oTom%C3%A9Pr%C3%ADncipeDobra'

Seems like the parser uses somewhere the wrong file encoding.
curr_S%C3%A3oTom%C3%A9Pr%C3%ADncipeDobra should be curr_SãoToméPríncipeDobra

from py-xbrl.

do you have any idea on how to fix it please?

I looked at the label linkbase again and found that this has nothing to do with the file encoding after all. The href attribute of the linkbase is simply url-encoded here.

<loc 
  xlink:href="currencies-2014-09-01.xsd#curr_S%C3%A3oTom%C3%A9Pr%C3%ADncipeDobra" 
  xlink:label="curr_SãoToméPríncipeDobra" 
  xlink:type="locator"/>

Now I am getting the same error you described earlier... 😄
Seems like this was a bug that was introduced in the latest versions of the package.

I will now check why the submission you provided fails with the error message KeyError: 'bus'.

from py-xbrl.

Found the issue. There is always this one report which is structured slightly different...
The creator of this report defines the namespace "bus" for every xml-element instead of just defining it once at the top of the submission.
The parser currently only uses the namespace-prefix map defined by the xmlns attributes at the root element. This is why it can'T find the corresponding namespace for the prefix 'bus'.
I will have a look at the error in the next few days and hopefully have enough time to fix it before the weekend.
