How to load enemies according to enemy list?

I have a game scene, but with different levels.
I have many enemy prefabs for the entire game, for example, I have 30 different enemy prefabs.

Now what I want to do is: I load this scene, but with different level information, which contains different enemy informations, for example, only 10 of the enemy prefabs will be used in this level.
How to do this? or how to design the level information?

One approch is using Resources.Load, but I’m not sure if this is the best way to do this.

IMHO, you should prepare xml files for level settings, load xml file for the current level and based on values in it, gather relevant data. e.g.,

SettingsLevel1.xml:

<LevelSettings>
     <EnemyList>
           <Enemy>
              EnemyPrefab1
           <Enemy>
           <Enemy>
              EnemyPrefab2
           <Enemy>
           ....
     </EnemyList>
     <LevelSounds>
           <BackgroundSound>
                BackgroundMusicLevel1.mp3
           </BackgroundSound>
           <GunSound>
                GunSoundLevel1.mp3
           </GunSound>
     </LevelSounds>
     ....
</LevelSettings>

Now based on the values, you can then load stuff from resources folder dynamically.
