.find_tag_in_hierarchy(current_hash, keys, path = []) ⇒ Object

This method recursively searches for a tag in a nested hash structure.

  • ‘current_hash`: The current level of the hash being searched.

  • ‘keys`: An array of keys representing the path to the desired tag.

  • ‘path`: An array to keep track of the current path (used for constructing the full path of the tag).
