Replace A if B=C



  • Hi,

    Not really sure how to phrase my query but here goes!
    I am trying to run a replace on an XML formatted as below:

    <TxnHeader>
    <StoreId>XXXX</StoreId>
    <TillNumber>1</TillNumber>
    <TxnNumber>XXXX</TxnNumber>
    <StartDate>2020-03-19T13:12:15</StartDate>
    <TxnType>X</TxnType>
    </TxnHeader>

    There are thousands of these in the file, all of which have a much longer set of details for the lines of the transactions (this is just a view of the transaction header), and I need to replace the Till Number with 91 for every one of these that has a hade in march (2020-03).

    I am sure its possible with a RegEx but have no skills past simple find and replaces, hoping someone here can help!



  • Hi, @jaevwyn and All,

    If I correctly understood you, you want that the value of the TillNumber attribute is changed by the number 91 ONLY IF the value of the StartDate attribute is prior to the date 2020-04-01

    If so, the following regex S/R should work :

    SEARCH \d+(?=</TillNumber>\R.+\R<StartDate>(19\d\d|20[01]\d|2020\-0[123]))

    REPLACE 91

    Of course, select the Regular expression search mode and, may be, the Wrap around option

    Best Regards,
