Class TagScanner

public class TagScanner extends Object implements Scanner, Serializable

TagScanner is an abstract superclass, subclassed to create specific scanners. When asked to scan the tag, this class does nothing other than perform the tag's semantic action. Use TagScanner when you have a meta task to do like setting the BASE url for the page when a BASE tag is encountered. If you want to match end tags and handle special syntax between tags, then you'll probably want to subclass CompositeTagScanner instead.

Constructor Summary
	TagScanner() Create a (non-composite) tag scanner.

Method Summary
Tag	scan(Tag tag, Lexer lexer, NodeList stack) Scan the tag.
