This system has a professional validating XML editor that provides four document views: an Enhanced Grid View for structured editing, a Database/Table View to show repeated elements in a tabular fashion, a Text View with syntax coloring for low-level work, and an integrated Browser View, which supports both CSS and XSL style sheets.XML Spy 3.0.7 includes many improvements in the area of XML-Data/BizTalk and W3C XML Schema support as well as bug fixes for the issues reported by customers since the 3.0 release. The new version also includes many small changes that work together to improve the overall performance and stability of XML Spy. This version update contains a new incremental validating parser that fully supports Document Type Definitions (DTD), Document Content Description (DCD), XML-Data Reduced (XDR), and BizTalk, and contains support for the current W3C XML Schemas.
