XML Notepad is a simple application that assists in the building of rapid prototypes of XML applications. It allows authors to rapidly build and edit small sets of XML data as a test bed during the development of XML-based applications. With XML Notepad, you can create XML document prototypes quickly, easily, and in an iterative fashion, using familiar metaphors.
XML Notepad offers an intuitive and simple user interface that graphically represents the tree structure of XML data. Working with the standard building blocks of XML (Elements, Attributes and Text), authors are able to create reproducible data structures that can be easily filled.
