    Hi , @KenJapan 

    Thanks for your response! The Latest time stamp is "20240619091000" which is "2024-06-19 09:10:00". Right?

    The  "20240619091000" is later then "20240619090000".

     

    Best Regards,

    Yueyun Zhang

    vyueyunmsft_0-1718848991001.png

     

    You can refer to my flow:

    vyueyunmsft_1-1718849104850.png

     

    xpath(xml(json(concat('{ "root": ', string(outputs('Compose')?['body'] ), ' }') )) ,'/root/*')

    xpath(item(),'name(/*)')

     

    concat(
    substring(replace( replace(last(sort(body('Select'))) , '_','' ) , 'x003' , '' ),0,4) , '-',
    substring(replace( replace(last(sort(body('Select'))) , '_','' ) , 'x003' , '' ),4,2) ,'-' ,
    substring(replace( replace(last(sort(body('Select'))) , '_','' ) , 'x003' , '' ),6,2),' ',
    substring(replace( replace(last(sort(body('Select'))) , '_','' ) , 'x003' , '' ),8,2) , ':',
    substring(replace( replace(last(sort(body('Select'))) , '_','' ) , 'x003' , '' ),10,2) , ':',
    substring(replace( replace(last(sort(body('Select'))) , '_','' ) , 'x003' , '' ),12,2) )

     

    outputs('Compose')?['body']?[replace( replace(last(sort(body('Select'))) , '_','' ) , 'x003' , '' )]?['wind']?[0]

    outputs('Compose')?['body']?[replace( replace(last(sort(body('Select'))) , '_','' ) , 'x003' , '' )]?['windDirection']?[0]
