regexp_replace not working in etext template

Summary:

regexp_replace not working in etext template

Content (required):

We have a requirement to remove extra semicolon from the string. Using regexp_replace, we are able to acheive it but it is working in etext template.

Ex: 'test;test1;test2;;;;;;test3;;' -> 'test;test1;test2;test3'

Can anyone suggest why regexp is not working in etext template. do we have any alternative solution to this ?
