Most one sided beating taken by a fighter that won?

[Bushbaby]

Mickey Ward/Sanchez. Ward almost only literally landed 2 left hooks to the body and they ended the fight after he took a sustained beating.

khan vs garcia

khan was schooling him like a little girl before getting low blowed thus not fully functional and getting caught with a lucky punch...

Ali vs. Foreman

Ali was getting the hell beat out of him, and has since admitted that he suffered terrible damage in that fight, particularly to the body.

I've never seen a fight change direction so quickly and dramatically as that fight.

Everyone thinks Ali built his career on his trilogy with Frazier, but the truth is, beating Foreman in such dramatic and unlikely fashion is his Ali's most noteworthy career achievement.

Ali became a legend that day.

This is not a good choice. Ali did not get beaten up anywhere near to the level you are describing. He was on the ropes a lot, but the fight was close dude. That lead right hand landed on Foreman's jaw from the beginning. You need to go and rewatch it.

Almost win after a beating: Tyson vs Douglas

When a battered and eye swollen Tyson landed the Hail Mary uppercut and Douglas went down, many thought Douglas wasn't getting up, which lead to the "long count" controversy.

Douglas got back up and the rest is ... Almost a fairy tale.

Bradley vs pacquiao...bradley was getting the sh it beat out of him and lost 11 of 12 rounds yet still managed to win the fight

Alvarado was getting his ass handed to him before he KO'd Prescott

That is a good shout. Prescott was boxing his ears off and Alvarado's face was a mess before Breidis inevitably gassed.
