 \section{\class{wxXmlDocument}}\label{wxxmldocument}
 
 This class holds XML data/document as parsed by XML parser in the root node.
 
 wxXmlDocument internally uses the expat library which comes with wxWidgets to parse the given stream.
 
+A simple example of using XML classes is:
+
+\begin{verbatim}
+wxXmlDocument doc;
+if (!doc.Load(wxT("myfile.xml"))
+    return false;
+
+// start processing the XML file
+if (doc.GetRoot()->GetName() != wxT("myroot-node"))
+    return false;
+
+wxXmlNode *child = doc.GetRoot()->GetChildren();
+while (child) {
+
+    if (child->GetName() == wxT("tag1")) {
+
+        // process text enclosed by <tag1></tag1>
+        wxString content = child->GetNodeContent();
+
+        ...
+
+
+        // process properties of <tag1>
+        wxString propvalue1 = child->GetPropVal(wxT("prop1"), wxT("default-value"));
+        wxString propvalue2 = child->GetPropVal(wxT("prop2"), wxT("default-value"));
+
+        ...
+
+    } else if (child->GetName() == wxT("tag2")) {
+
+        // process tag2 ...
+    }
+
+    child = child->GetNext();
+}
+\end{verbatim}
