Hi all,
I've written a new filter function called trim.
It returns the first part of a value up to the first occurance of a
separator.
If the separator is not found it just returns the value.
Example:
maybe you have a values like this
destination=München;Landsberg;Augsburg;Ammersee
destination=Kaufbeuren;Neugablonz;Mauerstetten;Pforzen
and you want just the first part "München", or "Kaufbeuren"
'${destination|trim:;}'
will do the trick.
with
destination=München/Landsberg/Augsburg/Ammersee
destination=Kaufbeuren/Neugablonz/Mauerstetten/Pforzen
use
'${destination|trim:/}'
Find attached the new TrimFilter.java a diff for ValueBuilder.java
Ciao,
Franco
