Examples of org.htmlparser.tags.Tag

org.htmlparser.tags.Tag
Tag represents a generic tag. This class allows users to register specific tag scanners, which can identify links, or image references. This tag asks the scanners to run over the text, and identify. It can be used to dynamically configure a parser. @author Kaarle Kaila 23.10.2001
