QXmlEdit is a simple XML editor based on qt libraries. Its main features are unusual data visualization modes,
nice XML manipulation and presentation and it is multi platform. It can split very big XML files
into fragments, and compare XML files. It is one of the few graphical Open Source XSD viewers.

The XML editor widget is based on a library that can be imported and used in other applications.

It is relased under GNU LGPL V2 license and requires Open Source edition of the Qt4 or Qt5 libraries.
