The Mars Project “PDFXML Inspector” works great as an ePub editing tool.
If you’ve just created an ePub and now you want to make a small change, the normal approach is to rename the file with a “zip” extension, extract the contents, make the change, and then repackage the contents.
Fortunately, there’s a better way, but I’m not sure if it’s been mentioned.
It’s from the Mars Project over on Adobe Labs, and it’s called the “PDFXML Inspector”.
