GLib has a simple XML api, which can be found at http://developer.gnome.org/doc/API/2.0/glib/glib-Simple-XML-Subset-Parser.html

There aren't any tutorials that I could find on the internet. I covered the XML parser in my book for the calendar application in the last chapter, however.

As a simple overview. Basically, you populate the structure of functions. Then, you call the parsing function. The file is parsed top-down, which calls one of the six functions every time a new element is opened/closed, an error occurs, data is retrieved, or a comment is hit.

Create a new GMarkupParser function, defining start_element(). Check element_name in that function until "cnu". Then, use the attribute value. You use g_markup_parse_context_new() to create a new GMarkupParseContext. Then, calling g_markup_parse_context_parse() will walk through the whole XML file, calling functions in your GMarkupParser for every element.
