Converti file BibTex in voci di database usando Python

Vecchia domanda, ma al momento sto facendo la stessa cosa usando Pybtex libreria, che ha un parser integrato:

from pybtex.database.input import bibtex

#open a bibtex file
parser = bibtex.Parser()
bibdata = parser.parse_file("myrefs.bib")

#loop through the individual references
for bib_id in bibdata.entries:
    b = bibdata.entries[bib_id].fields
    try:
        # change these lines to create a SQL insert
        print b["title"]
        print b["journal"]
        print b["year"]
        #deal with multiple authors
        for author in bibdata.entries[bib_id].persons["author"]:
            print author.first(), author.last()
    # field may not exist for a reference
    except(KeyError):
        continue
