abstract boolean	matches(XPathNode node, XPathContext context) Determines if the given node is matched by this Pattern with respect to the given context.

Method Detail

getDefaultPriority

public abstract double getDefaultPriority()

Determines the priority of a PatternExpr as follows:

  From the 19991116 XSLT 1.0 Recommendation:
  + If the pattern has the form of a QName preceded by a

    processing-instruction(Literal) then the priority is 0.
  + If the pattern has the form NCName:* preceded by a 
    ChildOrAttributeAxisSpecifier, then the priority is -0.25
  + Otherwise if the pattern consists of just a NodeTest 
    preceded by a ChildOrAttributeAxisSpecifier then the
    priority is -0.5
  + Otherwise the priority is 0.5

Returns: the priority for this PatternExpr

matches

public abstract boolean matches(XPathNode node, XPathContext context)

Parameters: node the node to determine a match for context the XPathContext

Returns: true if the given node is matched by this Pattern

Throws: XPathException when an error occurs during evaluation
