Package org.htmlparser
The basic API classes which will be used by most developers when working with
the HTML Parser.
Node | Specifies the minimum requirements for nodes returned by the Lexer or Parser. |
NodeFactory | This interface defines the methods needed to create new nodes. |
NodeFilter | Implement this interface to select particular nodes. |
Remark | This interface represents a comment in the HTML document. |
Tag | This interface represents a tag (<xxx yyy="zzz">) in the HTML document. |
Text | This interface represents a piece of the content of the HTML document. |
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.
