Since the books are published in what would be valid HTML 4 if it had a document type declaration for each document, an XML parser unfortunately won't get you anywhere. XML parsers by definition function only on XML, not on tag soup.

If you still want to go that way, maybe upgrading the documents to XHTML with tidy works.
