Firstly, why are you trying to write your own validator rule rather than
using the existing 'validwhen' rule? See the documentation on validwhen
[1] for examples of how to do what you want with that.
If you really do want to set up your own validator rule for some reason,
you would use it the same as the standard rules: in validation.xml you
set depends to the name of the validation rule ('confirm' in this case;
then you include the html:javascript [2] tag in your form and supply the
appropriate onsubmit handler on the html:form tag. See the Resources
section [3] of the validator guide for some links to tutorials and
articles which should get you up and running.
