public class DefaultText extends NodeImpl implements org.w3c.dom.Text
Text interface inherits from CharacterData 
 and represents the textual content (termed character data in XML) of an 
 Element or Attr. If there is no markup inside 
 an element's content, the text is contained in a single object 
 implementing the Text interface that is the only child of 
 the element. If there is markup, it is parsed into the information items 
 (elements, comments, etc.) and Text nodes that form the list 
 of children of the element.
 When a document is first made available via the DOM, there is only one 
 Text node for each block of text. Users may create adjacent 
 Text nodes that represent the contents of a given element 
 without any intervening markup, but should be aware that there is no way 
 to represent the separations between these nodes in XML or HTML, so they 
 will not (in general) persist between DOM editing sessions. The 
 normalize() method on Node merges any such 
 adjacent Text objects into a single node for each block of 
 text.
