XML Text Data Automatic Analysis and Transformation with Tree Convertor

Semi-structured documents in xml are ubiquitously in todaypsilas computer science applications, since XML has become the standard format for data exchange. It is consider a common format of future data. The present XML grammar is analyzed, and new text format is used to express XML data. Moreover, some new concept modes are puts forward according to some special forms of XML data and their validity and correctness is proven; at the same time, the grammar is proven to be simplified. Corresponding analysis algorithm of automatic machines is also developed and analyzed in connection with some corresponding special XML grammar forms. Transformation of data documents is of special importance to use XML as the universal data interchange format on the Web. Data transformation is used in many tasks that require data to be transferred between existing, independently created WWW-oriented applications.
