"Sorry for all you have experienced." Yes it is grammatically correct and it is used usually to apologies for one's deeds for which the other person has experienced something bad. More complete sentence would be. "Sorry for what you have gone through because of me" The first sentence is used more often because the cause is implied.

yeah...it is correct. it is often used when two people were in bad circumstances and the other one is the trouble maker :) nevertheless, nowadays people rarely to use it and simply feel it is only bad thing happen to anyone else

这句话是对滴 我觉得也可以用在书面语 意思就是说,对你经历的一切的一切的我很惋惜/悲恸/伤感/抱歉.... 应该是可以用到书面语的,毕竟书面语也是来源于口语的嘛~就例如上古汉语时期,那时候口语跟书面语基本上一样的:)
