This presentation proposes a method to automatically generate XML schema transducer. A transducer is a program that takes an XML document based on some schema A as input and outputs an XML document based on another schema B while preserving information. Our method generates a transducer by a pair of XML documents that contains the same information based on schema A and B respectively. First, our method makes a mapping by using position of each occurrence of a text value included in both documents. Next, it generates a transducer that extracts text values from tree structure of schema A and embeds them into the tree structure of schema B. Moreover, our method is capable of handling recurrence in schema structure. Most of related works that transduce schemas use similarity of names of XML elements or similarity of schema structure. Their target is partly modified schema. Whereas, our method can generate transducer, even in the case of greatly different schemas or if same names of XML elements are used for different meaning in schema A and B.
