Abstract

We propose simplifying the editing of structured documents that conform to Backus-Naur Form (BNF) grammars, by exposing and operating on the grammar itself. We introduce an original grammar view that supports browsing and editing of structured documents and is coordinated with the document view. The grammar view presents document element types in context to better support document editing. Both shading and font size scaling are used to create a focus area in the grammar view making it more scalable for larger grammars. We present an implementation of a grammar view for XML documents, in our XML editor, Xeena for Schema.
