+\section{\class{wxXmlNode}}\label{wxxmlnode}
+
+Represents a node in an XML document. See \helpref{wxXmlDocument}{wxxmldocument}.
+
+Node has a name and may have content
+and properties. Most common node types are {\tt wxXML\_TEXT\_NODE} (name and
+properties are irrelevant) and {\tt wxXML\_ELEMENT\_NODE} (e.g. in {\tt <title>hi</title>} there is
+an element with name="title", irrelevant content and one child ({\tt wxXML\_TEXT\_NODE}
+with content="hi").
+
+If wxUSE\_UNICODE is 0, all strings are encoded in the encoding given to Load
+(default is UTF-8).
