/home/web/.gem/gems/oga-2.16/lib/oga/xml/parser.rb:251:in `parser_error': Unexpected doctype name, expected doctype closing tag instead on line 1 (LL::ParserError)It seems to be throwing the error when the word "public" is not capitalized in a doctype. Not sure if this is a WONTFIX or not since PUBLIC is probably correct, but it does seem a bit unforgiving. I'm hotfixing it for now with a REGEX to replace with the right casing.
For the record I'm using Oga to parse out millions of html files from the geocities archive. It is less brutal about re-writing the output document than nokogiri is. The fairly weird site I got this exception with is: https://geocities.gallery/Heartland/7792/
