Oxygen XML Editor

Oxygen offers support for importing database data, MS Excel files and text files into XML documents, that can be further converted into other formats using the Transform features. The user can examine the database contents and select the table to be exported using the database browser. It is possible to refine the data source by editing the generated SQL select statement in order to join multiple tables or to use advanced SQL expressions. Oxygen can generate an XML Schema from the database structure.
