Hi @mickael-menu
I want to know the number of pages a subchapter of a chapter have, how can I do that ?
As per my observations EPUBPositionsService have a function makePostitions which divide a chapter into multiple positions but it doesn't have any info about the subchapter ?
Please suggest how can I relate that ?
Thanks regards

It's not possible. The positions count is computed using the resources bytes and has no knowledge of the HTML DOM.
