Enclosing class:

StaxExtractingProcessor

public static class StaxExtractingProcessor.LimitedStaxHandler
extends java.lang.Object

A base implementation to be extended to handle the elements within the matched elements. For example a <person> that contains <firstname> and <lastname> elements that need to be combined into a single value. "Bob Smith" The default implementation is a very thin wrapper on a string buffer and will simply collect all characters. All implementations should produce their results via the toString method which merely reflects the value of the accumulator. The most common use will be to maintain flags turning on/off capture of a selected number of sub elements (i.e. just the names but not the age or sex from a <person> element.
