This Python 3 package provides two scripts, auxtobib and auxtoxml, which take a LaTeX .aux file as input.
auxtobib fetches the bibtex entries for all the articles cited in the document from
INSPIRE. auxtoxml return an XML file containing the titles of the articles.
To install the package in your home directory, run
python3 -m pip install inspiretools --user
The script requires Python 3.4+. It uses pyinspire, see https://bitbucket.org/ihuston/pyinspire.
Given a LaTeX .aux file, simply execute
auxtobib paper.aux
and the bibtex entries will be printed to stdout. If you want to save them
into a .bib file, simply use
auxtobib paper.aux > bibliography.bib
The script to generate an XML file works analogously,
auxtoxml paper.aux > bibliography.xml
The script blgtobib will fetch only bibtex entries which are not already in
the .bib file associated with your project. It uses the bibtex log file
associated with the LaTeX project. For example,
blgtobib paper.blg >> bibliography.bib
will append new entries to bibliography.bib.
