fn-Remove managed metadata

When I do a query on a field (managed metadata) and put these data in an email I get a result like this

Sint-Truiden|3c177046-7264-4f31-a412-873c8e243cb7

I've tried to use fn-remove in the set variable task as

var=fn-Remove(var,|)

but then I get in the mail fn-Remove(Sint-Truiden|3c177046-7264-4f31-a412-873c8e243cb7,|)

I want to have only 'Sint-Truiden' in the message.

 Any suggestions?
