Yup. This works fine. Digester is a great tool! One thing I'm looking at
is how to combine it with a set of regular expression rules for the
elements and attributes. Something like:
<command id="123">
<user username="stefan"/>
</command>
With a property list:
command.id=/^\d+$/
user.username=/^[a-z0-9]+$/
And make this part of the validation process. I'm interested in your
thoughts about this. Is this something to add to the Digester core code
or something that I should move to my own classes?
