If you're desperate you could try 'lifting' - When DD was day trained (12 years ago lol) each night when I went to bed (around 10pm) I would get her up, sit her on the toilet, whisper "do wees Claire", she would pee while leaning on me, I would put her back to bed, she would sleep. She was still in a nappy but a REALLY deep sleeper and if I didn't her nappy would be SO wet, the sheets would all be wet every morning!

Otherwise, I think its a developmental thing and unless you can leap out of bed every morning and wake them up before they pee, you have to wait it out Have to say I'm not a fan of cold turkey (sorry!) because like Kiwimum says, its a brain/bladder connection and I would hate to be left laying in wet sheets so that I would 'learn' to wake up!

It's really normal to still be wet at night, for a lot of children bn dry at night comes a lot lot later than day.
my #1 day TT at 2yrs old in the blink of an eye but wasn't until around 4yrs that he was dry by night - and even that it was a total accident - like your DD his nappy was usually still soaked through at night until one night i forgot to put one on, and wham he was dry (i guess he realised he didn't have one but i didn't) basically after that I bought a few brolly sheets - and yeah we had a few accidents - but for the most part he stayed dry.
I did restrict drinks in the evening (simply bcos i noticed when he drank a lot after dinner he WOULD wet), and on the way to bed id send him to the loo - even if i knew he went only half an hour ago- just a good habbit.

#2 was dry at night a few weeks after bn dry in the day at 2 1/4yrs - but had a stage after a tummy bug where he needed to go back into nappies-started soaking them through so i took them off him bcos i KNEW he could be dry at night - he had a few wet beds (with the brolly sheet) decided he didn't much like that, and went back to being dry.

This is exactly what we did. Neither of them ever had a dry nappy so one night we just took it away and they stayed dry, it must be a psychological thing where they know they have a nappy on so it is okay to go.

I posted on this AAGGEESS ago. Olivia turned five and said "Big girl's don't wear nappies" and stopped wearing them. She was saturated at night on and off for a couple of weeks and has been mostly dry since. I'm definitely in the "Leave them to it" camp.

I just got this in an email today from the sleep store, made me feel a bit better about DD2 regressing back into a night nappy!
