Structure detection on simple chapters

madeinlisboa · 06-15-2011, 06:25 AM

Hi,
i'm very confortable with regexps, but I can't make the structure detection work with these very simple chapters headers:

Code:

Chapter 1.<br>

I tried to drill down to the simplest code, but it just doesn't work:

Code:

//*[re:test(., "(Chapter|Book|Section|Part|Prologue|Epilogue)\s", "")]

Plase, help me.

It doesn't look like Chapter is in a tag. It needs to be in a tag to be work properly.

OK, thanks. I thought that by indicating a pattern, Calibre could parse the chapter. Like /Chapter \d+\.\<br\>/

It can match a pattern but once it finds the match it references it to the current tag. Since it's XHTML references for links must point to a tag. So if your chapters are not in separate tags every one will match the same tag (duplicates are removed) and if I remember correctly it won't reference the body tag. So you get nothing.

I found a great solution and I would like to share. Fortunately the search/replace is done before the chapter detection, so all you have to do is search eg.

Code:

Chapter\s*(\d+)

and replace with eg.

Code:

<h2>Chapter \1</h2>

. This way the chapters are properly found and converted.
