regex: Lookbehind not supported?

[Joerg Schober]

Hi,

trying to add hierarchy. For this, I try to extract "SA" from jobname

D_SA_1040.pdf



The used regex is

(?<=[a-zA-Z]{1}_)[a-zA-Z]{2}



It does not work. Is lookbehind supported by Switch?



Kind regards,

Jörg

Lookbehind is indeed not supported.



I assume you are using this regular expression in the Search field of the Job.NameProper variable. There Switch only matches the first occurrence, so [a-zA-z]{2} would also return SA.

Thanks Freddy for the reply.



There are also other filenames that are different (SE_MM_1804, ...), so the regex needed in production enviroment is

(?<=[a-zA-Z]{1,2}_)[a-zA-Z]{2}



How could i solve this issue. Is a script expression possible?

Supports javascript lookbehind (with variable length)?

It seems most languages only supports lookbehind (if they supports) with fixes length.



Kind regards,

Jörg

If I understand correctly you want to extract the different segments of the name. Should not be a a problem in a script expression.



Nameproper.split("-")



Or did I misunderstand you

A script expression to retrieve "SA" part would be:



job.getNameProper().split("_")[1];
