[AccessD] A2003 - Build a List/Array from Tokens in a blurb

[Darren - Active Billing]

Hi Team

if I had a field with the following blurb...

Dear [FirstName],
Today is [NameOfDay] and the date is the [DateOfMonth] of [NameOfMonth].
Kind Regards,
{SignatoryName}

I can see in that blurb there are 5 tokens surrounded by Square and or Curley brackets.
How could I run though that text and build a list of the 5 tokens such that I can produce a list/array like...

[FirstName]
[NameOfDay] 
[DateOfMonth]
[NameOfMonth]
{SignatoryName}

Many thanks in advance.

Darren
