Node has a name and may have content and attributes.
Most common node types are @c wxXML_TEXT_NODE (name and attributes are irrelevant)
- and @c wxXML_ELEMENT_NODE (e.g. in @c \<title\>hi\</title\> there is an element
- with name="title", irrelevant content and one child @c wxXML_TEXT_NODE
- with content="hi").
+ and @c wxXML_ELEMENT_NODE.
+
+ Example: in <tt>\<title\>hi\</title\></tt> there is an element with the name
+ @c title and irrelevant content and one child of type @c wxXML_TEXT_NODE
+ with @c hi as content.
If @c wxUSE_UNICODE is 0, all strings are encoded in the encoding given to
wxXmlDocument::Load (default is UTF-8).
