Where can I find a WML validator?

To make sure that your WML code is proper, you should use a WML validator.

The first address for WML (and any XML) validation is the W3C QA Markup Validation Service.

A WML validator is part of the Zygo tools. The validator is written in Perl and is both available as an online utility and for download.
