Method Detail

parseTag

protected static void parseTag(Lexer lexer,
                               Node node,
                               short mode)

Parameters:

lexer -

node -

mode -

moveToHead

protected static void moveToHead(Lexer lexer,
                                 Node element,
                                 Node node)

Move node to the head, where element is used as starting point in hunt for head. Normally called during parsing.

Parameters:

lexer -

element -

node -

parseDocument

public static Node parseDocument(Lexer lexer)

HTML is the top level element.

XMLPreserveWhiteSpace

public static boolean XMLPreserveWhiteSpace(Node element,
                                            TagTable tt)

Indicates whether or not whitespace should be preserved for this element. If an xml:space attribute is found, then if the attribute value is preserve, returns true. For any other value, returns false. If an xml:space attribute was not found, then the following element names result in a return value of true: pre, script, style, and xsl:text. Finally, if a TagTable was passed in and the element appears as the "pre" element in the TagTable, then true will be returned. Otherwise, false is returned.

Parameters:

element - The Node to test to see if whitespace should be preserved.

tt - The TagTable to test for the getNodePre() function. This may be null, in which case this test is bypassed.

Returns:

true or false, as explained above.

parseXMLElement

public static void parseXMLElement(Lexer lexer,
                                   Node element,
                                   short mode)

XML documents.

parseXMLDocument

public static Node parseXMLDocument(Lexer lexer)
