Extracting text from a column of strings

[#1]

Hello,

I am a bit of a novice when it comes to scripting in JMP, and I am trying to write a script that would be able to extract specific numbers from a string and create new columns for each one. Each number would always follow the characters 'DX' or 'DY' For example:

D113U_NTCH_CM_MEAS_CD_SEM_{2UM_X6_NTCH_CM_IMAGE}_DX7DY11SDX11SDY15_2024-12-06_18-57-42.jpg

I would want to extract and create these columns:

Of course, I would like to repeat this process over an entire column of data. I'd appreciate any advice. Thanks!

Do you know beforehand all the possible patterns (DX, DY, ....)? Is it always located in the same place (after }_ and before date)?

If I had a column full of those filenames, I would do a Cols -> Recode, top-left Red Triangle -> "Replace String", and then enter "S?D[XY](\d+)" and replace with "%\1%" with "Use regular expressions" turned on.  Then you can split the column (Cols -> Utilities -> Text to Columns...") and enter "%", which will give you 6 new columns, with the prefix, DX, DY, SDX, SDY, and suffix, e.g.:

Column 1 2	Column 1 3	Column 1 4	Column 1 5	Column 1 6	Column 1 7
D113U_NTCH_CM_MEAS_CD_SEM_{2UM_X6_NTCH_CM_IMAGE}_	7	11	11	15	_2024-12-06_18-57-42.jpg

Then you can rename the columns to DX, DY, etc.

If your real data is more complicated this process might need to be a bit more complicated as well.

Nice : )
maybe start with 

word(8, filename,"_")

such that it works as well for lot DX11A.

Here is an alternative approach.  

Given the data table

The below script will directly create

Names Default To Here( 1 );

// Create and example data table
dt = New Table( "Example",
	Add Rows( 1 ),
	New Column( "File",
		Character,
		"Nominal",
		Set Values(
			{
			"D113U_NTCH_CM_MEAS_CD_SEM_{2UM_X6_NTCH_CM_IMAGE}_DX7DY11SDX11SDY15_2024-12-06_18-57-42.jpg"
			}
		)
	)
);

// Add the new columns to the data table
dt << New Column( "DX" );
dt << New Column( "DY" );
dt << New Column( "SDX" );
dt << New Column( "SDY" );

For Each Row(
	// Separate the section of the File name into just the DX,DY,SDX,SDY part
	string = Word( 1, Substr( :file, Contains( :file, "_DX" ) + 1 ), "_" );
	// Change the string into a assignment statements
	Substitute Into( string, "SDX", ";:SD_X=", "SDY", ";:SD_Y=", "DX", ";:D_X=", "DY", ";:D_Y=", "_", "" );
	string = Substr( string, 2 ) || ";";
	// Execute the assignment statements
	Eval( Parse( string ) );
);
