Class XSLTHelper

java.lang.Object

net.grinder.plugin.http.tcpproxyfilter.XSLTHelper

public final class XSLTHelper
extends Object

Helper functions for style sheets.

When calling methods that don't have parameters from a style sheet, don't forget the call braces or you'll end up with a no-op.

This class has static methods for consistent behaviour between JDK versions. With instance methods the XSLTC implementation in Java 5.0 needs the instance to be passed as the first argument, whereas the Xalan implementation in Java 1.4 does not.
