node
- The NodeInfo representing the Element or other node to be tested against the Patternanchor
- The anchor node, which must match any AnchorPattern subpatterncontext
- The dynamic context. Only relevant if the pattern
uses variables, or contains calls on functions such as document() or key().XPathException

treat this the same as a false result)public void export(ExpressionPresenter presenter) throws XPathException

- the expression presenter used to display the structureXPathException
- if the export fails, for example if an expression is found that won't work
