Constructor Details

Stripper

protected Stripper()

Default constructor for use in subclasses

Stripper

public Stripper(Mode stripperRules)

create a Stripper and initialise variables

Parameters:

stripperRules - : defines which elements have whitespace stripped. If null, all whitespace is preserved.

Method Details

setPreserveAll

public void setPreserveAll()

Specify that all whitespace nodes are to be preserved

getPreserveAll

public boolean getPreserveAll()

Determine if all whitespace is to be preserved (in this case, no further testing is needed)

setStripAll

public void setStripAll()

Specify that all whitespace nodes are to be stripped

getStripAll

public boolean getStripAll()

Determine if all whitespace is to be stripped (in this case, no further testing is needed)

setController

public void setController(Controller controller)

Set the Controller to be used

isSpacePreserving

public boolean isSpacePreserving(int nameCode)

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

Parameters:

uri - The namespace URI of the element name

localname - The local part of the element name

Returns:

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

                  throws TransformerException

Callback interface for SAX: not for application use

Overrides:

startElement in class ProxyEmitter

Parameters:
