To access massive and various HTML documents that are in the web using wireless Internet equipments, another WML document that is equal to the HTML document must be written, In the case Web documents written by HTML are massive, the construction of a WML site with the same information needs much cost of space and time, This paper designs and implements the HTML-XML converter that alleviates such a problem. The HTML-WML converter translates the Web document written by HTML to the WML document for portable wireless equipments, The HTML-XML converter has advantages that it reconstructs WML document dynamically according to portable wireless equipments and processes various image formats such as GIF, JPG, BMP, and so on, The HTML-WML converter can be used as not only a utility of the WML editor but also a real-time converter on wireless Internet.

In order to present wireless Internet users with previously created HTML contents and applications, it is essential to research and develop the technology to efficiently convert HTML documents into documents and further provide a way to edit the WML documents. This paper describes the design and development of a WML converter and WML editor The WML converter can convert HTML pages in real time into WML documents that are suitable for the WAP environment. The WML editor enables creation and modification of WML documents in a WYSIWYG fashion. These tools enable the previous services based on HTML documents to be easily adapted to the wireless environment. The developed WML converter can be installed on a proxy server to support real time conversion of Web contents. It is superior to other converters in terms of the various image formats it supports and the improvements on the conversion of the link and frame tags. Users can continuously browse via links and also view frames. Automatic dividing of large WML documents into WML cards md user defined conversion rules are also supported. The WML editor is also integrated with the converter and provides an integrated WYSIWYG environment for creating, converting and publishing WML documents.

In this paper, we describe a design and implementation of the Wireless Markup Language(WML) compiler to deploy wireless Internet services effectively. The WML compiler translates textual WML decks into binary ones in order to reduce the traffic on wireless links that have relatively low bandwidth to wireline links and mitigate the processing overhead of WML decks on, wireless terminals that have relatively low processing power to fixed workstations. In addition, it takes over the overhead of eXtensible Markup Language(XML) well-formedness and validation processes. The WML compiler consists of the lexical analyzer and parser modules. The granunar for the WML parser module is LALR(1) context-free grammar that is designed based on XML 1.0 and WML 1.2 DTD(Document Type Definition) with the consideration of the Wireless Application Protocol Binary XML grammar. The grammar description is converted into a C program to parse that grammar by using parser generator. Even though the tags in WML will be extended or WML DTD will be upgraded, this approach has the advantage of flexibility because the program is generated by modifying just the changed parts. We have verified the functionality of the WML compiler by using a WML decompiler in the public domain and by using the Nokia WAP Toolkit as a WAP client. To measurethe compressibility gain of the WML compiler, we have tested a large number of textual WML decks and obtained a maximum 85 %. As the effect of compression is reduced when the portion of general textual strings increases relative to one of the tags and attributes in a WML deck, an extended encoding method might be needed for specific applications such as compiling of the WML decks to which the Hyper Text Markup Language document is translated dynamically.

The desire of achieving abundant and various information in Web-sites through portable devices is increased as the mobile communication technology is matured. WML(Wireless Markup Language) is the fundamental language to fill up the those desires. The number of commercial WML sites which can be accessed by PCS(Personal Communication System) over the Internet are growing rapidly worldwide. In this paper, a WML authoring tool which can author easily the homepage suitable for PCS is designed and implemented. The usability of the proposed WML authoring tool was confirmed by using UP.SDK simulator over the Internet.
