\section{\class{wxXmlResource}}\label{wxxmlresource}
+This is the main class for interacting with the XML-based resource system.
+
+The class holds XML resources from one or more .xml files, binary files or zip archive files.
-This class holds XML resources from one or more .xml files
-(or derived forms, either binary or zipped -- see manual for
-details).
+See \helpref{XML-based resource system overview}{xrcoverview} for details.

+Initializes only a specific handler (or custom handler). Convention says
+that the handler name is equal to the control's name plus 'XmlHandler', for example
wxTextCtrlXmlHandler, wxHtmlWindowXmlHandler. The XML resource compiler
-(xmlres) can create include file that contains initialization code for
-all controls used within the resource.
+(wxxrc) can create include file that contains initialization code for
+all controls used within the resource. Note that this handler should be
+allocated on the heap, since it will be delete by

\func{wxXmlResource*}{Get}{\void}
-Singleton accessors.
Gets the global resources object or creates one if none exists.
\constfunc{long}{GetVersion}{\void}
-Returns version information (a.b.c.d = d+ 256*c + 256\verb|^|2*b + 256\verb|^|3*a).

-\func{int}{GetXMLID}{\param{const wxChar* }{str\_id}}
-
-Returns a numeric ID that is equivalent to the string id used in an XML
-resource. To be used in event tables.
-Macro XMLID is provided for convenience
+\func{int}{GetXRCID}{\param{const wxChar* }{str\_id}, \param{int }{value\_if\_not\_found = -2}}
+Returns a numeric ID that is equivalent to the string ID used in an XML
+resource. If an unknown \arg{str\_id} is requested (i.e. other than wxID\_XXX
+or integer), a new record is created which associates the given string with
+a number. If \arg{value\_if\_not\_found} is \texttt{wxID\_NONE}, the number is obtained via
