You may find that, whatever you do, nothing helps until her body is physically ready. So the best advice I can give you is don't stress.
I read all the info that said once they have a few dry nights take them out of nappies - but age 4 came and went and DD1 never did have a dry night. We tried removing the nappies but then we just got soaking wet beds.
At around 6 they referred her to the enuresis clinic, mainly because she couldn't hold on for long in the day either.
They tried all manner of incentives, sticker charts, drugs (which worked in a limited way but affected her adversely in other ways), goodness knows what. The only thing that eventually worked was an alarm, but it meant terrible broken nights and we were only allowed to keep it a very short time under NHS rules, and she regressed after we stopped.
After nothing worked they started getting cross and suggested psychiatric tests to see if there were any underlying issues. At this point I got scared, lied and said she was dry, and we left. I put her in dry nites and we forgot all about it.
At the age of 9, she just grew out of it. For about a year after that she would regress a bit if she got stressed and we would have a wet bed. She's 16 now and you would never know she ever had a problem. It took a long time, but we got there. And I really wish above everything else that we had not put her through all that. I look back and all that sticker chart stuff was just awful, because she couldn't do anything about it. We were trying to offer rewards for something she could not control. 
DD2 was spontaneously dry at night at only 3, so it really was nothing to do with my parenting. DD1 just took a long time to physically mature enough.
Your DD will be dry at night. It might be next month. it might be 5 years down the line. But she will be dry. :)
