Tag name in HTML

Some of the HTML files do not have tagname with financial corrections and financial data can not be extracted from them.
For example, this format
name = “core: CashBankOnHand”
Does not exist in some files and cash is in unnamed tags
Extracting financial data from these file types is impossibleenter link description here

Hi
Please answer this question

I suspect like the rest of the data here, CH just publish what they’re given. Someone else asked a while back if there was a standard taxonomy and no-one answered that…

If it helps, here’s what CH said about this, and there’s a link to the bulk download of financial data which may help you (e.g. you can compare how data is returned across all the relevant filings).
