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 -
  - moveNodeToBody
```
static void moveNodeToBody(Lexer lexer,
                           Node node)
```
    moves given node to end of body element.
    
    Parameters:
    
    lexer - Lexer
    
    node - Node to insert
  - 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)
```
  - badForm
```
static void badForm(Lexer lexer)
```
    errors in positioning of form start or end tags generally require human intervention to fix.
