 - **Output Builder**: Many projects want a different parsing result. Some wants to group the attributes, some wants to skip an attribute or tag, some wants index number with each property, and some wants to group some properties in array. So FXP v5 come up with 3 output builders. User can customize their behavior and use their own custom builder too.
