hello, piotrrzysko, thank you for your guidance. I implemented the function to parse values ​​on multiple json paths at the same time, based on OnDemandJsonIterator. Advantages of PathsBasedJsonParser

• Avoid json node repeated construction
• Can specify the json node value type, the default is string type（If a json node is list or object type, only string type can be returned）
• Can parse object and array values ​​at the same time
