startSelectedParentNode
public Receiver startSelectedParentNode(FleetingNode node,
int locationId)
throws XPathException
- Signal that an element has been found that matches the selection that this
Watch is looking for. This method is called by the ConstraintChecker while
processing the startElement event that matches the selection. For this purpose,
any attributes selected by the last step in the selection are ignored
- Specified by:
startSelectedParentNode
in interface Watch
- Parameters:
node
- locationId
- @throws net.sf.saxon.type.ValidationException
May be raised if the constraint implemented by this
Watch is violated
- Returns:
- a Receiver to be notified of all events starting with the startElement/startDocument event
for the matched element, and ending with the endElement event for that element.
- Throws:
ValidationException
- May be raised if the constraint implemented by this
Watch is violated

- Signal that a node (other than an element) that matches the selection
has been found.
