Modifying Text by Cutting and Pasting
This Example describes a method to cut and paste the
Text in a DOM document. Methods which are used to cut and paste text in the DOM
Document are described below :-
Element root = doc.getDocumentElement():-direct access
to the root of the DOM document.
Element place = (Element) root.getFirstChild():-retrives
the first child of the root.
Text name = (Text) place.getFirstChild().getFirstChild():-creates
a text node and gets the sub child of the node named place.
Text directions = (Text)
place.getLastChild().getFirstChild():- makes a text node and access the sub
child of the node name place. name.getLength():-gets the length of the nodelist
name.
name.deleteData(offset, count):-This method deletes
data from a text node. Here offset specifies where to begin removing characters.
offset value starts with zero
directions.substringData(offset, count):-This method
retrives a substring of the full string from the specified range.
name.appendData(bridge):-adds a String to the end of
the text node.

Output of the program:-
Name before cutting is: Roseindia .Net
Direction before cutting is: Girish Tewari
name after cutting is: Roseindia
name after pasting is: Roseindia Tewari |
