TreeViewer displays the input file in a graphical tree based interface. This sample highlights the error handling capabilities of the parser, demonstrating how the parser can recover from many types of common errors.

Requirements:

• Xerces-J is loaded on your computer.
• Either:
• JDK 1.1.8 and Swing1.1.1 are is loaded on your computer.
• Or:
• Java 2 (jdk1.2.2) is loaded on your computer.

Source code:

• TreeViewer.java
• TreeView.java
• DOMTree.java
• DefaultImages.java

To run TreeViewer:

1. open up a MS-DOS command line window
2. set the path to the jdk\bin directory
3. change directory to the latest xerces-1_4_4 directory
4. invoke the TreeViewer sample

On Windows:

The easiest way to do this is to create a .bat file using the Notepad editor. Then TreeViewer can be invoked by double clicking on the file name or icon. The following command lines assume that both the jdk and the xerces-1_4_4 directories are located directly below the c: drive.

With jdk1.1.8:

	set PATH=%PATH%;c:\jdk1.1.8\bin set CLASSPATH=%CLASSPATH%;c:\xerces-1_4_4\xerces.jar;c:\xerces-1_4_4\xercesSamples.jar set CLASSPATH=%CLASSPATH%;c:\Swing-1.1.1\swingall.jar cd c:\xerces-1_4_4 java ui.TreeViewer data/personal.xml

With jdk1.2.2:

Swing is included in the Java 2 release and it doesn't required a separate reference.

	set PATH=%PATH%;c:\jdk1.2.2\bin set CLASSPATH=%CLASSPATH%;c:\xerces-1_4_4\xerces.jar;c:\xerces-1_4_4\xercesSamples.jar cd c:\xerces-1_4_4 java ui.TreeViewer data/personal.xml

Parse your own XML file instead of data/personal.xml
