The development of WAP needs to transcode HTML pages into WML pages.As the meta-language of markup language
XML can be used to solve the transcoding problem as the form of intermediate conversion by using the flexibility of it.Firstly
it completes the transcoding work from HTML pages to XML pages
and then completes the transcoding work from XML pages to WML pages.It achieves the whole transcoding from HTML pages to WML pages via the bridge of XML.Finally
it is proved that the intermediate transcoding model have more accuracy and higher efficiency than other algorithm through experiment.
