Might have helped if I gave you a sample XML def?
<package name="org.stjude.ct.ui">
<message>
<field name="MESSAGE" min="0" max="*">msg</field>
<field name="MESSAGE_TYPE" min="1" max="1">type</field>
</message>
</package>
Then using the XSLT transform on this XML you get the Java file:
package org.stjude.ct.ui;
/**
* Static constant values used in the UI layer
*
* ***** Do not alter this file *****
*
* This file was produced from the source UIConstants.xml
* See the comments in that file for information on how to
* update and produce this file
*
*/
public abstract class UIConstants {
public static final String MESSAGE = "msg";
public static final String MESSAGE_TYPE = "type";
}
Now you have your constants for your Java code. Since they originated
from an XML file you can reference the XML file in any other
transform/transformer you might have (use aggregation in the sitemap if
you're not comfortable with the document() function and the caching
implications)...
