Allow namespace prefixes other than 'None' in PageXML

See original GitHub issue

Eynollah, e.g., produces PageXML files that use an explicit prefix (xmlns:pc="").

calamari_ocr/ocr/dataset/datareader/pagexml/, however, expects the prefix to be ‘None’ and throws an error when processing an eynollah pagexml.

When I change line 120 of from

ns = {"ns": root.nsmap[None]} 


ns = {'ns' : ''}

it works. I’m not sure if you can generalize the namespace dictionary to cover both output styles. Maybe xpath’s local-name function (instead of lxml find or findall) is an alternative.

Okay, just wanted to “clarify” the most obvious mistake. Luckily, I receive the same error using your files. I will examine this and hopefully find the reason!

Thanks for testing @alexander-winkler . I will close this and merge #259
