xmloperator is an XML editor, suitable for editing data oriented documents.
The software is open source, Java written, released under a BSD-style license. It requires J2SE 1.4 and uses Xerces-J and Xalan-J from the Apache Software Fondation.
xmloperator displays a tree view of the nodes of the document. When you select one node of the document, it appears in a detailed view, adjacent to the tree view. You can open several instances of the tool in order to work simultaneously on several documents.
