public class XSLTProcessorApplet
extends java.applet.Applet

Provides applet host for the XSLT processor. To perform transformations on an HTML client:

1. Use an <applet> tag to embed this applet in the HTML client.
2. Use the DocumentURL and StyleURL PARAM tags or the `setDocumentURL(java.lang.String)` and `setStyleURL(java.lang.String)` methods to specify the XML source document and XSL stylesheet.
3. Call the `#transformToHTML` method to perform the transformation and return the result as a String.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.
