WML is based on XML, and is a content format for devices that implement the WAP Wireless Application Protocol specification, such as mobile phones, and preceded the use of other markup languages now used with WAP, such as XHTML and even standard HTML. WMLScript is the dialect of JavaScript used for WML pages and is part of the WAP.

This little book was quite helpful when WML and WMLScript first entered the scene at the turn of the century. It introduced a new technology in a very simple and accessible way as only O'Reilly and Associates can. However, as processing power in handsets increases, it is likely WML will be phased out in the future. Thus at this point it isn't even worthwhile to learn it. I give this book two stars out of respect to how useful it was when it was first published.

I thought this book was great. It struck the right balance between being a comprehensive primer on the topic, having enough detail if you decide you need it and not going into too much detail about stuff that is dealt with elsewhere - like CGI programming or generating pages from languages like Perl. If you want that then buy Leraning Perl or CGI programming on the World Wide Web.
