Examples of org.htmlparser.PrototypicalNodeFactory

org.htmlparser.PrototypicalNodeFactory
te a inner class that is a subclass of TextNode new TextNode () { public String toPlainTextString() { String original = super.toPlainTextString (); return (org.htmlparser.util.Translate.decode (original)); } }); Parser parser = new Parser (); parser.setNodeFactory (factory);

Here is an example of using a custom link tag, in this case just printing the URL, which illustrates registering a tag:
```
 class PrintingLinkTag extends LinkTag { public void doSemanticAction () throws ParserException { System.out.println (getLink ()); } } PrototypicalNodeFactory factory = new PrototypicalNodeFactory (); factory.registerTag (new PrintingLinkTag ()); Parser parser = new Parser (); parser.setNodeFactory (factory); 
```

            "<a href=\"http://www.yahoo.com/\">Yahoo!</a><br>" +
            "<a href=\"http://www.excite.com\">Excite</a>" +
            "</body>" +
            "</html>"
        );
        parser.setNodeFactory (new PrototypicalNodeFactory (
            new Tag[] {
                new MetaTag (),
                new TitleTag (),
                new LinkTag (),
