All Implemented Interfaces:

Receiver, javax.xml.transform.Result

public class StylesheetStripper

extends Stripper

The StylesheetStripper refines the Stripper class to do stripping of whitespace nodes on a stylesheet. This is handled specially (a) because it is done at compile time, so there is no Controller available, and (b) because the rules are very simple

Constructor Detail

StylesheetStripper

public StylesheetStripper()

Method Detail

getAnother

public Stripper getAnother()

Description copied from class: Stripper

Get a clean copy of this stripper

Overrides:

getAnother in class Stripper

setStylesheetRules

public void setStylesheetRules(NamePool namePool)

Set the rules appropriate for whitespace-stripping in a stylesheet

isSpacePreserving

public byte isSpacePreserving(int nameCode)

Decide whether an element is in the set of white-space preserving element types

Overrides:

isSpacePreserving in class Stripper

Parameters:

nameCode - identifies the element being tested

Returns:

ALWAYS_PRESERVE if the element is in the set of white-space preserving element types, ALWAYS_STRIP if the element is to be stripped regardless of the xml:space setting, and STRIP_DEFAULT otherwise

isSpacePreserving

public byte isSpacePreserving(NodeInfo element)

Decide whether an element is in the set of white-space preserving element types. This version of the method is useful in cases where getting the namecode of the element is potentially expensive, e.g. with DOM nodes.

Overrides:

isSpacePreserving in class Stripper

Parameters:

element - Identifies the element whose whitespace is possibly to be preserved

Returns:

true if the element is in the set of white-space preserving element types

characters

public void characters(java.lang.CharSequence chars,
                       int locationId,
                       int properties)
                throws XPathException

Handle a text node

Specified by:

characters in interface Receiver

Overrides:

characters in class Stripper

Throws:

XPathException
