Re: [Htmlparser-developer] HTMLParser 1.2 - 1.3

[Derrick O. <Der...@ro...>]

The visitor paradigm is one way.
See StringBean which implements NodeVisitor.
You could pass all nodes to the same method:

    public void visitTag (Tag tag) { do_something (tag); }
    public void visitEndTag (Tag tag) { do_something (tag); }
etc.
    void do_something (Node node) { <do something> }
