GenDoc (formerly GenDiapo) is an XML Editor based on a existing project, MerlotXML. It can use two kinds of plugins (DTD and/or action). The DTD plugin can be used to customize the editor for a DTD, and an action plugin can be used to publish documents in HTML or PDF format. The editor is composed of 3 views: tree view, attribute view for current element, and a "styled view". The aim of styled view is to show the document with a visual aspect.

XMLProperties is a utility class which stores and retrieves property lists (key-value/s pairs) from an XML document. It is in a way similar to the java.util.Properties file but with one main difference: it can store more than one property value for a given property key. Each property key corresponds to an XMLPropertyValues object which may contain one or more property values.
