Creating and Modifying XML Documents - Beginning Java 2 SDK

Java Reference

In-Depth Information

That's all the code we need. You now need to make sure all the imports are in place for the source files

we have modified. In addition to what was already there, the Element.java file needs:

import org.w3c.dom.Document;

import org.w3c.dom.Attr;

The SketchFrame.java file needs the following import statements added to the original set:

import java.nio.ByteBuffer;

import java.nio.channels.FileChannel;

import org.w3c.dom.Node;

import org.w3c.dom.NodeList;

import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.ParserConfigurationException;

You should also have added the following imports to the SketchModel.java file:

import javax.swing.JOptionPane;

import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.ParserConfigurationException;

import org.w3c.dom.Document;

import org.w3c.dom.DOMImplementation;

import org.w3c.dom.DOMException;

If everything compiles, you are ready to try exporting and importing sketches.

Try It Out- Sketches in XML

You can try various combinations of elements to see how they look in XML. Be sure to copy the

sketcher.dtd file to the directory in which you are storing exported sketches. If you don't, you won't

be able to import them since the DTD will not be found. Don't forget you can look at the XML using

any text editor and in most browsers. I created the sketch below.
