Interface for deciding whether a particular element is to have whitespace text nodes stripped

Method Summary

Modifier and Type	Method and Description
void	export(ExpressionPresenter presenter) Export this rule as part of an exported stylesheet
int	isSpacePreserving(NodeName nodeName, SchemaType schemaType) Decide whether an element is in the set of white-space preserving element types
ProxyReceiver	makeStripper(Receiver next) Make a filter to implement these space-stripping rules, or null if no filtering is necessary

Method Detail

isSpacePreserving

int isSpacePreserving(NodeName nodeName,
                      SchemaType schemaType)
               throws XPathException

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

Returns:

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

Throws:

XPathException - if the rules are ambiguous and ambiguities are to be reported as errors

makeStripper

ProxyReceiver makeStripper(Receiver next)

Make a filter to implement these space-stripping rules, or null if no filtering is necessary

Parameters:

next - the Receiver that is to receiver the filtered event stream

Returns:

a filter in the form of a ProxyReceiver, or null

void export(ExpressionPresenter presenter)
     throws XPathException
