After you catch the main legendary (dialga, palkia, giratina) go to lake verity and mesprit will be in the cave in the middle of the lake. Talk to it and then it will flee and appear on your map app.

Its not Azelf its Mesprit that flees and you get it by using the Pokemon tracker app and you wil need a Pokemon with mean look so Mesprit does not flee.
Mesprit does flee from the battles normally at the beginning. But if you manage to inflict damage on it then when you see it again it will still have the damage to it. The best way I found to catch Mesprit is to get a level 30-40 Pokemon that knows Mean Look, I evolved my gastly as i found my captured Haunters didnt know Mean Look. Then give your Pokemon that knows mean look a quick claw. Track down Mesprit using the Poketech app (forgot what it is called, my apologies >.
its most important is to find mesprit, it is otherwise usless
You can find Mesprit in Verity Cavern. Head to Lake Verity and use surf till you find a cave. Inside will be Mesprit. However, it will run away so you will need the Marking Map app to find it.

You find them all at separate lakes. You can catch Uxie and Azelf at their lakes. Mesprit flees again when you go to her lake. You need to use the map marker poketch app to find it. PS: Don't fly towards the Mesprit. It will go to a different spot then. Use your bike or run to get to it.

After she flees from the island, she roams the sinnoh region. Then you can use your poketch app that you use to find mesprit, and hunt it down.
first go to jubilife city. there a place is it a bulding with 4 red flags. go in there. talk to the man in the purple dress. he give you it. then you go between two places. when mesprit is over you head, go in tall grass. when you been chalenged, it may is mesprit.
To catch Mesprit you need to surf to the middle of lake Verity. There you will find a cavern in which Mesprit lives. After you talk to it, it flys away! When that happens, Professor Rowan talks to you. After he leaves, get out of the cavern and start chasing Mesprit! To chase Mesprit, use your poketch app Marker Map to find Mesprit's icon(it blinks!). Instead of flying to the nearest city, which makes it run away, walk or bike all the way to its icon and look around in the nearest patch of tall grass. it often runs away, so be careful!

Go to the top of Mount Coronet, using the cave system from Hearthome's side. Once you have reached the top, you will find Team Galatic's Boss's waiting for you, and they will challenge you to a fight. When you have beaten them, and have beaten the final boss, you can catch Dialga/Palkia (depending on whether it is diamond or pearl).
After you defeat the Pokemon League (Elite Four and Champion) go to Verity lake, the one closest to your home town. Once there, surf into the middle of the lake and enter the small island in the middle. Talk to Mesprit, it will show the Pokedex entry picture of it in the middle of the screen, then Mesprit will flash (disappear and appear) several times before banishing. If you don't already have the Poketch app "Marking Map" get it. A little face appears where Mesprit is. Track it down to that area, and you can find it like a normal wild Pokemon(in grass, on water, etc). After one move it flees the battle, but you can still track it down using the "Marking Map" app. If you want to keep Mesprit in the battle, get a Pokemon whose ability is Arena Trap (Dugtrio, Diglett, Trapinch), or have a Pokemon that knows Mean Look(Stops the Pokemon from escaping).
