Development Assistance Reading config files

Code:

x:
  boolean: 1

How can the values of x.boolean in a config.yml be read where the user can specify an unlimited amount of x's?

For example, how can I read the PRISMARINE.boolean:

Code:

STONE
  boolean: 1
PRISMARINE
  boolean: 0

if the user can specify 'STONE', 'PRISMARINE' and an unlimited number of blocks?

I'm new to plugin development... and I've tried decompiling plugins and reading tutorials with not much luck. Any help would be greatly appreciated!

 

@PaperJump Here is a sample config that will work with my example:

Code:

a:
  b:
    c: '¤'
  d:
    c: 'µ'

c is the variable, b and d are the identifiers.
They are in the section a.

Code:

ConfigurationSection section = getConfig().getConfigurationSection("a");
//you don't need that if it's in the root, as opposed to under a section (in this case a)
HashMap<String, String> map = new HashMap<String, String>();
//you can store them however you like, maps are easy
for (String key : section.getKeys(false)) {
//the false means don't search deep (so only give 'b' and 'd', not 'c'
    map.put(key, section.getString(key+".c"));
}

Random additional fact for when you find yourself not needing a label - this is perfectly valid:

Code:

a:
- b:
  c:
  d:
- b:
  c:
  d:

In this case, you would use get("a"), and cast it to List<LinkedHashMap>.
