Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

Parameters:

elemName - integer code identifying the name of the element within the name pool.

type - integer code identifying the element's type within the name pool.

locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.

properties - properties of the element node

Throws:

XPathException - if an error occurs

endElement

public void endElement()
                throws XPathException

Handle an end-of-element event

Specified by:

Throws:

XPathException - if an error occurs

getPath

public String getPath(boolean useURIs)

Get the path to the current location in the stream

Parameters:

useURIs - set to true if namespace URIs are to appear in the path; false if prefixes are to be used instead. The prefix will be the one that is used in the source document, and is potentially ambiguous.

Returns:

the path to the current location, as a string.
