The largely dispersive and different forms of data have resulted in more and more difficulties to the modern data processing. In order to unify the data form to help data operating and processing, the issue how to transform the various data forms into unified XML (Extensible Markup Language)format is discussed. In the computer network, the Metadata Model to the file data of different forms in the source data is applied, according to the predefining XML cyclostyle, with unified specification in the structure of format specification file and extracting data to make further processing, and finally outputting after transforming into XML code. The concrete strategy and process to realize the flow is designed: making it true that distracting data from TXT file and then transforming into XML code, completing such research work as design of data format specification file, development of data route-chosen tool, design and development of language analysis tool. The result showed: The technique of Metadata Model not only can process the source data structure form in terms of line that other kind of products can do, but also has the ability to process the non-line (character strings and
