open

public void open()

Description copied from class: ProxyReceiver

Start of event stream

Specified by:

open in interface Receiver

Overrides:

open in class ProxyReceiver

startElement

public void startElement(int namecode,
                         int typecode,
                         int locationId,
                         int properties)
                  throws XPathException

Abort the parse when the first start element tag is found

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

Parameters:

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

typecode - 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

isTerminated

public boolean isTerminated()

Determine whether the parse terminated because the first start element tag was found

processingInstruction

public void processingInstruction(String target,
                                  CharSequence data,
                                  int locationId,
                                  int properties)
                           throws XPathException

Handle xml-stylesheet PI

Specified by:

processingInstruction in interface Receiver

Overrides:

processingInstruction in class ProxyReceiver

Parameters:

target - The PI name. This must be a legal name (it will not be checked).

data - The data portion of the processing instruction

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 - Additional information about the PI. The following bits are defined:

CHECKED

Data is known to be legal (e.g. doesn't contain "?>")

Throws:

XPathException

getAssociatedStylesheets

public Source[] getAssociatedStylesheets()
                                  throws TransformerException

Return list of stylesheets that matched, as an array of Source objects

Returns:

null if there were no matching stylesheets.

Throws:

XPathException - if a URI cannot be resolved

TransformerException
