ACADEMIA | Extract all text from a specific heading

Dear Obsidian Community,

I know that AlanG has posted an excellent guide regarding the following question but my limited dataview/regex savvy quite frankly won’t allow me to adapt his user case to mine
(Coalesce headings into one file? - #2 by AlanG).

I am trying to extract text belonging to specific headings in the following way

I guess having the chapter headings is a tall order but failing that having only the text under the “draft” headings extracted would facilitate my workflow immensely

(knowing that the heading has the following format if that is important :
###### <font style=“color: #737373”>✎DRAFT</i></font>
<hr>)

✎DRAFT

Thank you all in advance for any help you might be able to provide me.

Have a nice day !
