Blogger scraper

I have few blog on blogger before few years. And now i forgot google user for them.
I want to download them and make new blogs on my new google user. If i know google user and password is easy - i will make a backup of entire blog, but a must find a scrapper or copy paste by hand but this is over 300 recipes
Can suggest a blogger scrapper

There are custom scrapers available but you will have to find html tags and in most cases regex to parse text from the individual posts. It will be hard. So you will have to stick to manual mode. Copy-paste manually to make a backup.
