Package org.htmlparser


package org.htmlparser
The basic API classes which will be used by most developers when working with the HTML Parser.

The Parser class is the main high level class that provides simplified access to the contents of an HTML page. A wide range of methods is available to customize the operation of the Parser, as well as access specific pieces of the page as Nodes.

The NodeFactory interface specifies the requirements for a developer to have the Parser or Lexer generate nodes. Three types of nodes are required: Text, Remark and Tags. Tags contain lists of child nodes and attributes.

The only provided implementation of the NodeFactory interface is the PrototypicalNodeFactory which operates by holding example nodes and cloning them as needed to satisfy the requests for nodes by the Parser. By default, a Lexer is it's own NodeFactory, returning new TextNode, RemarkNode and undifferentiated Tagnodes (see the nodes package), but when the parser uses a lexer it replaces this behaviour with a PrototypicalNodeFactory to return a rich set of specific tags (see the tags package).

The NodeFilter interface is used by the filtering code to determine if a node meets a certain criteria. Some generic examples of filters can be found in the filters package.
