Python and the XML Document Object Model (DOM) with 4Suite

As with the Element constructor, the first argument to this constructor is the parent node, whose .doc attribute is a DOM Document node that carries the .createTextNode() factory method we need to create a DOM Text node.

# - - -   T e x t . _ _ i n i t _ _   - - -

    def __init__ ( self, parent, content ):
        """Constructor for Text

          [ parent is an Element object ->
              parent  :=  parent with a new text node added with
                          text=content
              return a new Text object representing that text ]
        """

        #-- 1 --
        # [ parent is an Element ->
        #     self.node  :=  a new DOM Text node with content=content ]
        self.node  =  parent.doc.node.createTextNode ( content )

Next, we attach the newly constructed DOM Text node to its parent DOM node.

        #-- 2 --
        # [ parent  :=  parent with self.node added as its next or
        #               only child ]
        parent.node.appendChild ( self.node )
