String.replaceAll not working in Groovy script

Alejandro59 ,

This is best case to use Template Engine feature of groovy.

Instead of [plc]pattern[plc] => use $pattern or $variable

In your case, variables are originalSender, finalRecipient, AP_Initiator etc

Now the script will just look like below (only replacement part)

import groovy.text.SimpleTemplateEngine
import java.time.*
//Here define what value needs to be replaced for each variable
def binding = [originalSender: '9928:12341234A', finalRecipient: '9928:12341234B', AP_Initiator: 'POP000106', TimeStampNormalized: System.currentTimeMillis(), TimeStampUTC: Instant.now().atZone(ZoneId.of("UTC"))]

def template = new SimpleTemplateEngine().createTemplate(new File('C:/Templates/Template.xml').getText('UTF-8')).make(binding)
log.info "Updated xml : ${template.toString()}"

By the way, you can quickly run the script here to see output.

Also wanted to point out why your script is not working.

[plc] - here it will find only p / l / c, but not plc

[, ] has to be escaped i.e., \[plc\]

Then \ has to be escaped again - so finally it will be '\\[plc\\]pattern\\[plc\\]'

Check here how it is done.
