How to remove a group of characters for each value from list/multivalue.

String of variable alert_type:

|detail.action=blocked|detail.devicename=hd03|detail.virus=fec_virus_macro_sic_1|detail.sha256=fd8a5b3ea9e59d3f863822cd2dddfbfded034f8ddad351c909732f18b1a82662|detail.md5=fecd3f3d9a9233c234bf0b455f73f65b

Objective:

Split the string by "|" and remove the "=" and followed characters.  Something like rstrip command however it wasn't working with multivalue.

E.g.

detail.action
detail.devicename
detail.virus
detail.sha256
detail.md5

It seems I need to used the foreach command however I'm not sure how i will used it.

If it was in SPL this expression would work in rex, but since you tagged it as transforms.conf, I don't know what adjustments you might need but at least it might get you part of the way there

 

\|?(?<name>[^=]+)[^\|]+\|?

Apologize I think I mistagged it. It was for SPL only.

It able to get the value of the first key (detail.action) after the split with "|". Is there a way I could get the rest of them?

Please clarify.  Is the field in question a string or a multi-value field?

The foreach command doesn't work on multi-value fields.

it was a string.

I need to split it with "|" then remove the values after the "="
