Method Summary

Node	createRemarkNode(Page page, int start, int end) Create a new remark node.

Node	createTagNode(Page page, int start, int end, Vector attributes) Create a new tag node.

Method Detail

createStringNode

public Node createStringNode(Page page,
                             int start,

Parameters:

page - The page the node is on.

start - The beginning position of the string.

end - The ending positiong of the string.

Throws:

ParserException

createRemarkNode

public Node createRemarkNode(Page page,
                             int start,
                             int end)
                      throws ParserException

Create a new remark node.

Parameters:

page - The page the node is on.

                          int end,
                          Vector attributes)
                   throws ParserException

Create a new tag node. Note that the attributes vector contains at least one element, which is the tag name (standalone attribute) at position zero. This can be used to decide which type of node to create, or gate other processing that may be appropriate.

Parameters:
