Easy way to get source files from doxygen documentation?

I have found the source for a game that I am interested in modifying, and it's in the form of doxygen "documentation".

Under "f开发者_运维百科iles" I get html files with names not related to the cpp and h files, and also line numbers.

I was wondering if there is a way to convert the doxygen documentation into regular cpp and h files.

How many files are there? If not too many, a manual copy-paste perhaps...

html2text is a python program that is pretty good at converting html to, well, text.
