docs: parse a single XML node
          
          A parsed XML document (from minidom.parse) is a tree of nodes
          of various types.  Each node is represented by an instance of the
          corresponding Python class (Element for a tag, Text for
          text data, Document for the top-level document).  The following
          statement constructs the name of a class method based on the type
          of node we're parsing ("parse_Element" for an Element node,
          "parse_Text" for a Text node, etc.) and then calls the method.
