XML Explorer is a extremely fast, lightweight XML file viewer. It can handle extremely large XML files. It has been tested on files as big as 300MB. It allows fast viewing and exploration, copying of formatted XML data, evaluation of XPath expressions, and XSD schema validation.
An expression library is included to store and manage commonly-used XPath expressions, much like Bookmarks in FireFox. It supports multiple document tabs, with support for middle-clicking to close tabs, and fully-featured, Visual Studio-style dockable panes.
