Reading and Writing RSS Feeds - Java 6 - page 514

The appendChild() method appends a new child below all other children of that parent.
The preceding statements produce this XML fragment:

<channel>
<link>http://www.cadenhead.org/workbench/</link>
</channel>

The appendChild() method also can be called with a String argument instead of a
node. A Text object representing the string is created and added to the element:

link.appendChild(“ http://www.cadenhead.org/workbench/” );

After a tree has been created and filled with nodes, it can be displayed by calling the
Document method toXML() , which returns the complete and well-formed XML document
as a String .

Listing 19.3 shows the complete application.
