The Python XML Tools collection is built on top of PyXML and features two GTK widgets: XmlTree and XmlEditor. The Python XML Tools are available from http://www.logilab.org/xmltools/. These packages are used to display XML files (XmlTree), as well as edit them (XmlEditor).

XmlTree displays XML files in a tree-like form, familiar to those who’ve used file browsers on Windows, KDE, or GNOME. This structure takes the form of a GTK widget—it’s derived from the GtkCTree Widget.

The API features several methods for setting the XML document for display, setting XPath filters for the tree, and a class for generating metadata about the tree.

In addition to API methods, the tree features configurable key bindings. For example, pressing an asterisk (*) recursively expands the selected node, while the / key closes them.

The XmlEditor is also a GTK widget, but XmlEditor allows for the editing of XML documents. It uses the aforementioned XmlTree for display. The structure available for editing is currently centered around a DTD, but may change to use schema at a later date.

In addition to a simple API for driving the editor, the XmlEditor also features an add_change_listener method that allows you to supply a callback function. The callback function is then executed whenever the Apply or Ok buttons are pressed on the editor.
