execute
public XObject execute(XPathContext xctxt)
throws TransformerException
- Overide the super method so that we can handle
match patterns starting with a function such as id()/

NodeTest.SCORE_OTHER.- Throws:
- TransformerException -
- Overrides:
- execute in class StepPattern
executeRelativePathPattern
public XObject executeRelativePathPattern(XPathContext xctxt)
throws TransformerException
- Execute the match pattern step relative to another step.
- Parameters:
xctxt - The XPath runtime context.- Returns:
NodeTest.SCORE_NODETEST,
NodeTest.SCORE_NONE,
NodeTest.SCORE_NSWILD,
NodeTest.SCORE_QNAME, or
NodeTest.SCORE_OTHER.- Throws:
