I am looking for Regex to extract the parameters of a SAP Form Routine.

The Form routine signature looks like the following:

FORM get_vbrk_data USING cs_bil_number TYPE VBELN CHANGING cs_vbrk TYPE vbrk cs_vbak TYPE vbak.

Challenge here is to get the name of the FORM routine -> get_vbrk_data

... AND the parameters:

USING -> cs_bil_number TYPE VBELN

CHANGING -> cs_vbrk TYPE vbrk AND cs_vbak TYPE vbak

The perfect format would be an result array with the following format:

[ "get_vbrk_data", "USING", "cs_bil_number", "TYPE", "VBELN", "CHANGING", "cs_vbrk", "TYPE", "vbrk", "cs_vbak", "TYPE", "vbak" ]

I tried to start with the following Regex:

\b(?:USING|CHANGING).*

But I am not able to process further.

CodePudding user response：

Observing your perfect format, you don't actually extract the parameters, but rather simply divide the Form routine without the leading FORM and the trailing . into its substrings:

s = "FORM get_vbrk_data USING cs_bil_number TYPE VBELN CHANGING cs_vbrk TYPE vbrk cs_vbak TYPE vbak."
console.log(s.slice(5, -1).split(' '))
