All Implemented Interfaces:
Feed

public class EmptyTextNodeRemoverFeed
extends ItemFeed

This class is used when a streaming template requests evaluation of a simple content constructor in streaming mode (that is, when it constructs a text, attribute, comment, or PI node based on the contents of the streamed document). It removes empty text nodes arriving on the input, and concatenates adjacent text nodes into a single text node.

Both a Feed and a Watch are needed because a simple content constructor operates on a sequence of nodes without simply atomizing the sequence.
