When I convert a book, I can go to Structure detection (see image) and insert the following expression in the "Detect chapters at (XPath expression
" and insert this expression
//*[re:test(., "Chapter", "i")]
then go to Chapter mark: and choose pagebreak and the conversion will split the HTML at every instant of the word chapter. Making the creation of a TOC easy.
My question is when I'm in the book editor and I choose to split at multiple locations (see image). Which expression can I insert here to have the same result? Currently, after merging the files, if I see the need I will save the book and back out then convert the book to accomplish my desired results. I would much prefer to be able to insert an expression here and do the same thing.
Edit: when I cut and paste the expression above into the edit book split area I get an error. Here are the 2 most common errors.
ERROR: Unhandled exception: <b>AbortError</b>:Cannot split on the <body> tag
ERROR: Unhandled exception: <b>AbortError</b>:The expression //*[re:test(., "Chapter", "i")] did not match any nodes
