XML Tree Editor

XMLTreeEdit displays XML files as tree views and allows basic operations: adding, editting and deleting text nodes and their attributes. The main goal is providing a simple tool to create/edit XML configuration files for users without knowledge of XML. Built in Free Pascal Lazarus, which allows easy compilation for different target platforms. Currently binary executables were produced and tested on Windows (XP, 7) and Ubuntu Linux (GTK2). For developers: there are two units listed separately to support XML configuration files in your application: XMLfile.pas - Lazarus/Free Pascal uXMLConfig.pas - Delphi (2007..XE2)
