[NTG-context] counting characters when dealing with XML

Dear list,

I have a question when dealing with XML.

Is there any way to write a conditional based on the number of
characters in a given field?

I mean, the following field:


If subtitle > 60 chars, then fontsize = 10pt.
If subtitle > 50 chars, then fontsize = 12pt.
If subtitle > 40 chars, then fontsize = 14pt.
If subtitle > 30 chars, then fontsize = 16pt.

How could I write these conditionals?

Many thanks for your help,
