Conversion and Regex Help

[thedevilsjester]

I have been having issues trying to get Calibre convert the ebooks I have and remove the header/footer information. I have tried different regex examples in an atempt to fix the various issues I am having, and with trial and error have managed to get decent regex working which strips most of the header and footer data, except for Chapter names like:

None but she knew its contents, or would have a glimmer of what it

Lightnings 5

meant if they did.

In the above, Lightnings is the chapter name, 'of what it' ends page 4, and 'meant if they did' begins page 5. I have a similar situation with the Book Title or Authors Name in the header.

Any help with the above situation?
