Ruby:如何查找与某些属性匹配的嵌套对象

def find_objects_with_attribute(obj, attribute, value)
  if obj.is_a?(Hash)
    obj.each do |key, val|
      if key.to_s == attribute && val == value
        puts "Found matching object: #{obj}"
      elsif val.is_a?(Hash) || val.is_a?(Array)
        find_objects_with_attribute(val, attribute, value)
      end
    end
  elsif obj.is_a?(Array)
    obj.each do |item|
      find_objects_with_attribute(item, attribute, value)
    end
  end
end

# 示例数据
data = {
  name: 'John',
  age: 30,
  address: {
    street: '123 Main St',
    city: 'New York',
    country: 'USA'
  },
  friends: [
    { name: 'Alice', age: 25 },
    { name: 'Bob', age: 35 }
  ]
}

# 查找名为'Bob'的朋友
find_objects_with_attribute(data, 'name', 'Bob')
