How to Fill Transform array using script ?

Hello!
I have a prefab in Resources folder. This prefab has script which has the following line in script:

 var AllItems: Transform[];

In Hierarchy I have objects, like Item1, Item2, Item3… Now i have to manually drag the objects in to this prefabs script.
But I need some kind of script to do this automaticaly for example at the Start() when the prefab is instantiated The script searches for i dont know - a word “Item” or what to add all objects with this name to the Transform array. How to script this ?

Thanks!

I would recommend using the function FindGameObjectsWithTag to find all the GameObjects Tagged with a specific tag and then fill your Transform array with the transforms of the found GameObjects.
