How to write X-notifier scripts.

To make your own script, you should be able to handle javascript and regular expressions. When the login form of your webmail provider is like this,

<form action="https://logins.foo.com/login" method="post">
  <input name="user">
  <input name="passwd" type="password">
  <input name="key" value="abc=12" type="hidden">
  <input value="Login" type="submit">
</form>

the corresponding script is as below. Save below codes as 'mymail.js'(or other name that ends with '.js') And install it in X-notifier preferences.
