Load txt file into a class

Hi. I have a .txt file that looks like this
Name A
1
2
3
Name B
3
2
1
Name C
11
22
33

The number of objects in this .txt file will change, and I want a way to load these into a struct.

 var itemDataBase : TextAsset;
 var itemList : String[]; // i don't wanna have to set a specific array size
 
 class itemStruct{
     var name;
     var cost;
     var health;
     var damage;
 }
 public var item : itemStruct[]; // i don't wanna have to set a specific array size
 function Start()
 {
     if(itemDataBase)
     {
         var itemCount = 0;
         itemList = (itemDataBase.text.Split("\n"[0]));
         for(line in ) // need this to loop once for every line in .txt file
         {
             item[itemCount].name =         itemList[line++];
             item[itemCount].cost =         itemList[line++];
             item[itemCount].health =     itemList[line++];
             item[itemCount++].damage =     itemList[line];
         }
     }
 }

Thanks.
