FREE Graphical XML Schema Editor. A fully featured XML Development Studio, including graphical and text based XML Schema Editor, XML editor, validation, intellisense, XPath & Web Service Tools, HTML Document Generator, XML Diff Tool and more.

Features: The biggest feature of this tool is that it is free. It is a graphical XML schema editor and XML editor. As a full featured development suit it contains several important development aids. The XML schema editor(XSD) is graphical and text based. You are able to visualize and edit the schema easily. Context sensitive parameters makes understanding XSD requirements easy. Drag & drop as well as cut & paste with several levels of undo makes the editing job easy. XML data binding that involves creating class libraries from the XSD schema is made easy by the studio. It reduces coding efforts and makes you more productive. The XML editor is aware of synt6ax and can thus validate the XML code against the standard as well as the XSD schema.

It integrates easily with the MS VB studio and combined features include graphical XML schema editor, XPath expression builder, web service browser, web method invocation, inferring of XSD from the XML. It is simple to explore the functions exposed by a web service. Individual web methods can then be called though the UI, which will automatically generate the XML required for the chosen method. XPath expression builder highlights the results of your XPath query in real time against any XML document. Code samples are provided. You can generate Cross browser HTML from your XSD Schemas. The documentation contains indexes, hyperlinks, each entity in the schema shows the complete XSD Code, with a textual description of its properties, diagram (while hot spots to link to child entities), all within collapsible sections so irrelevant information can be easily ignored. There`s a XML code comparator too.

Overall: Nice set of code development too. It is quite sophisticated for a free tool. It is quite easy to use too.
