Textinterface inherits from
CharacterDataand represents the textual content (termed character data in XML) of an
Attr. If there is no markup inside an element's content, the text is contained in a single object implementing the
Textinterface that is the only child of the element. If there is markup, it is parsed into the information items (elements, comments, etc.) and
Textnodes that form the list of children of the element.
When a document is first made available via the DOM, there is only one
Textnode for each block of text. Users may create adjacent
Textnodes 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
Nodemerges any such adjacent
Textobjects into a single node for each block of text.
