Thanks a lot

Hi @FP68 

 

ApplicationName2 =
VAR TagText = Disques_Global[TAGS]
VAR _Key = "Name="
VAR _Key2 = "ApplicationName="
VAR KeyPos = SEARCH ( _Key, TagText, 1, 0 )
VAR Key2Pos = SEARCH ( _Key2, TagText, 1, 0 )
VAR ValueStart = KeyPos + LEN ( _Key )
VAR SemiPos = SEARCH ( ";", TagText, ValueStart, 0 )
RETURN
IF (
    KeyPos = 0,
    BLANK(),
    IF (
        KeyPos <> Key2Pos + 11,
        IF (
            SemiPos = 0,
            MID ( TagText, ValueStart, LEN ( TagText ) - ValueStart + 1 ),
            MID ( TagText, ValueStart, SemiPos - ValueStart )
        )
    )
)

// TagText holds the whole "key=value; key=value; ..." string

 

VAR CleanText =
    SUBSTITUTE ( SUBSTITUTE ( TagText, "; ", ";" ), " ", "" )   // normalize spaces

 

// Try to find ;Name= anywhere mid-string
VAR PosSemicolon = SEARCH ( ";Name=", CleanText, 1, 0 )

 

// Also allow Name= at the very start
VAR PosStart = IF ( LEFT ( CleanText, 5 ) = "Name=", 1, 0 )

 

// True token start: either after ';' or at the beginning
VAR TokenStart =
    IF ( PosSemicolon > 0, PosSemicolon + 1, PosStart )

 

RETURN
IF (
    TokenStart > 0,
    VAR ValueStart = TokenStart + LEN ( "Name=" )
    VAR Remainder  = MID ( CleanText, ValueStart, 32767 )
    VAR Value      = LEFT ( Remainder, SEARCH ( ";", Remainder & ";", 1, 0 ) - 1 )
    RETURN Value,
    BLANK ()

how about using ";Name="?

Hi,
The colums can start with Name so ";Name" is not OK

Hi @FP68 

 

ApplicationName2 =
VAR TagText = Disques_Global[TAGS]
VAR _Key = "Name="
VAR _Key2 = "ApplicationName="
VAR KeyPos = SEARCH ( _Key, TagText, 1, 0 )
VAR Key2Pos = SEARCH ( _Key2, TagText, 1, 0 )
VAR ValueStart = KeyPos + LEN ( _Key )
VAR SemiPos = SEARCH ( ";", TagText, ValueStart, 0 )
RETURN
IF (
    KeyPos = 0,
    BLANK(),
    IF (
        KeyPos <> Key2Pos + 11,
        IF (
            SemiPos = 0,
            MID ( TagText, ValueStart, LEN ( TagText ) - ValueStart + 1 ),
            MID ( TagText, ValueStart, SemiPos - ValueStart )
