epubl

Could a regex program be made so that heading 2 or 3 would apply to any line that is separated from other blocks of texts (paragraphs) begins with "chapter"?

I am in the process of making ePub files out-of-copyright scanned books from Archive.org. Some problems in the scanned text files was that 1. It has a lot of spaces between words. For example, impossible: im possible 2. It doesn't have table of contents 3. So I would like to create some kind of program or Regex that would automatically fit together words that has been split, and automatcially creates a table of contents. How might I do this?
