Method Detail

isSpacePreserving

public byte isSpacePreserving(NodeName fingerprint)
                       throws XPathException

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

Specified by:

isSpacePreserving in interface SpaceStrippingRule

Parameters:

fingerprint - Identifies the name of the element whose whitespace is to be preserved

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

Throws:

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

addRule

public void addRule(NodeTest test,
           Stripper.StripRuleTarget action,
           StylesheetModule module,
           int lineNumber)
             throws XPathException

Add a rule

Parameters:

test - a NodeTest (*, *:local, prefix:*, or QName)

action - StripRuleTarget.STRIP or StripRuleTarget.PRESERVE

module - the stylesheet module containing the rule

lineNumber - the line where the strip-space or preserve-space instruction appears

Throws:

XPathException - if this rule is a conflicting duplicate

addRule

public void addRule(NodeTestPattern pattern,
           Stripper.StripRuleTarget action,
           int precedence,
           int minImportPrecedence)
             throws XPathException

Throws:

XPathException

getRule

public Rule getRule(NodeName nodeName)

Get the rule corresponding to a given element node, by finding the best pattern match.

Parameters:

nodeName - the name of the element node to be matched

Returns:

the best matching rule, if any (otherwise null).

export

public void export(ExpressionPresenter presenter)

Export this rule as part of an exported stylesheet

Specified by:

export in interface SpaceStrippingRule

Parameters:

presenter - the output handler
