what do you mean by "references" in this context?

if the document uses LaTeX,
the sectioning is represented in the .toc file
(but: this excludes non-numbered sections, a priori)
and  you can get it from a parsing of the .toc file
even without lua tools

from etoc manual at end of section 28. The TOC as a TikZ mind map

of course I expect this to be much more naive than what 
you are hinting at (hence my question about "references")
