类 TagScanner

java.lang.Object

org.htmlparser.scanners.TagScanner

所有已实现的接口:

java.io.Serializable, Scanner

直接已知子类:

CompositeTagScanner, JspScanner

public class TagScanner
extends java.lang.Object
implements Scanner, java.io.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.
