regex - How do I mutate a tritium variable string? -

i've fetched entire list of classes body variable so:

$page_code = fetch("self::body/@class")

but want grab 1 class out. tried using replace() , regex on variable contents think something's syntax:

$page_code {   text() {     replace(/[^a-z]*/, '')   }   log("@@@@@@@@@@@@@@ page code " + $page_code) }

i think code want is:

$page_code {   replace(/[^a-z]*/, '') } log("@@@@@@@@@@@@@@ page code " + $page_code)

since $page_code string, don't need open text() scope. also, log() statement should outside, or else log current value of $page_scope.
