Constructor Detail

StringNode

public StringNode(String text)

Constructor takes in the text string.

Parameters:

text - The string node text. For correct generation of HTML, this should not contain representations of tags (unless they are balanced).

StringNode

public StringNode(Page page,
                  int start,
                  int end)

Constructor takes in the page and beginning and ending posns.

start - The beginning position of the string.

end - The ending positiong of the string.

Method Detail

getText

public String getText()

Returns the text of the string line.

Specified by:

getText in interface Node

Overrides:

getText in class AbstractNode

setText

public void setText(String text)

Sets the string contents of the node.

Specified by:

setText in interface Node

Overrides:

setText in class AbstractNode

Parameters:

text - The new text for the node.

toPlainTextString

public String toPlainTextString()

Description copied from class: AbstractNode

Returns a string representation of the node. This is an important method, it allows a simple string transformation of a web page, regardless of a node.
Typical application code (for extracting only the text from a web page) would then be simplified to :

 Node node;
 for (Enumeration e = parser.elements();e.hasMoreElements();) {
    node = (Node)e.nextElement();
    System.out.println(node.toPlainTextString()); // Or do whatever processing you wish with the plain text string
 }
 

Specified by:

toPlainTextString in interface Node

Specified by:

toPlainTextString in class AbstractNode

toHtml

public String toHtml()

Description copied from class: AbstractNode

This method will make it easier when using html parser to reproduce html pages (with or without modifications) Applications reproducing html can use this method on nodes which are to be used or transferred as they were recieved, with the original html

Specified by:

toHtml in interface Node

Specified by:

toHtml in class AbstractNode

toString

public String toString()

Express this string node as a printable string This is suitable for display in a debugger or output to a printout. Control characters are replaced by their equivalent escape sequence and contents is truncated to 80 characters.

Specified by:

toString in interface Node

Specified by:

toString in class AbstractNode

Returns:

A string representation of the string node.

accept

public void accept(Object visitor)

Description copied from interface: Node

Apply the visitor object (of type NodeVisitor) to this node.
