BibteXML syntax

[zesaro]

The BibteXMLImporter only accepts xml files where tags have a syntax like <bibtex:author>. Otherwise JabRef does not read the data or even the file. Shouldn't it be possible to read files with normal syntax?
I created a few tests for this Importer. Two tests of them are ignored, because otherwise circleci would return an error.

The BibTeXML parser is implemented in a wrong way. BibTeXML is a DTD document. XML is namespace aware. Therefore, the document should be parsed namespace aware.

Proposal: Rewrite the whole BibTeXML parser using javax.xml.parsers.DocumentBuilderFactory.

Update: Schemas are available at https://github.com/Zearin/BibTeXML/tree/master/bibtexml/schema . I would propose to build on the XML Schema

I would like to take care of this issue. But in my opinion a JAXB parser would be easier than just using a DOM parser. Would this be also ok?

JAXB sounds like a good idea. Mabye you can reuse some of your code.

#1666 is merged, so I think this can be closed.
