right - lets diagonse thie before I get lynched by the mods :-)

I have the same zip as you. I tick "restore defaults" on all the conversion screens & convert to epub, then view that in calibre viewer - the only TOC entry is "start"

repeat - but tick auto generate toc on toc screen... same result

open epub with sigil and I can see that structure detection has done its thing and has added the h2 tags ,& has created 1 file per chapter -&, I am not seeing the benefit in the form of a viewable TOC -

so we are both apparently right - your structure detection code IS working but I am not getting a TOC to view ...

AHA

I think you explained that actually, 2 posts up.... I need to open & close with sigil to compete the TOC generation, & that works & is fine for me. others may want a calibre-only solution and that would be to modify the xpath ?

I was maybe close to the answer but still in the dark !

so model answer.
step 1:enable structure detect - no need to enable auto generate toc. convert to epub.
at this stage the fchapters have been tagged & the fepub has been split with 1 file per chapter
step 2 open & close epub in sigil.

one final query on xpah - I come unstuck if I try to modify the end bit ( or class = chapter bit) in order to add an AND - is that because it is no possible.

say I wanted to replace the @class = 'chapter' test with a test for bold roman numerals so I'd want somewthing like ( @class = 'bold' AND re:test( [XIV]+ ). I'm not too clear on the retest syntax but have tried lots of invalid permutations!

is that doable and could you give a model answer for that please.
