Re: [NTG-context] Help with typesetting footnotes in an HTML document

[Keith McKay via ntg-context <ntg-context@ntg.nl>]

Hi Denis,

Thanks for the code, I shall give this a try.

To get the html file I convert a docx file using a wordpress multisite 
app called Pressbooks, a book content management system for book 
publishing in various formats such as the web, pdf, epub and various xml 
flavours (see pressbooks.com). My interest was that docx files could be 
imported into pressbooks, edited and then exported as html which I then 
used in ConTeXt to produce pdf. Pressbooks has an open source option and 
they give instructions on how to self-host on a local web server, which 
is what I have done (see pressbooks.org). It is, I suppose, like using a 
sledgehammer to crack a nut, and the html files produced are quite 
complicated. I'm still in the experimental stage with it.

Before trying out Pressbooks, I had previously produced two 
books(novels) by converting docx files to epub using an epub extension 
to Libre Office, then edit/clean-up the epub using Sigil epub editor. 
Finally I extract the individual xhtml files and input into ConTeXt. 
That was much easier and the files much less complicated, however those 
books did not have footnotes so I shall have to check that out in Sigil. 
I'm still experimenting to get a simple workflow for the conversion of 
docx files to simple (x)html files.

Thanks again for the code.

Best Wishes

Keith
