public class PIGrabber
extends ProxyReceiver

The PIGrabber class is a Receiver that looks for xml-stylesheet processing instructions and tests whether they match specified criteria; for those that do, it creates an InputSource object referring to the relevant stylesheet

Constructor Detail

PIGrabber

public PIGrabber(Receiver next)

Method Detail

setFactory

public void setFactory(Configuration config)

setCriteria

public void setCriteria(java.lang.String media,
                        java.lang.String title)

setBaseURI

public void setBaseURI(java.lang.String uri)

Set the base URI

Parameters:

uri - the base URI

setURIResolver

public void setURIResolver(javax.xml.transform.URIResolver resolver)

Set the URI resolver to be used for the href attribute

Parameters:

resolver - the URI resolver

startElement

public void startElement(NodeName namecode,
                         SchemaType 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 - if an error occurs

isTerminated

public boolean isTerminated()

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

Returns:

true if the parse was terminated when the document element was encountered (as distinct from being terminated because of some exception condition, for example a parse error)

processingInstruction

public void processingInstruction(java.lang.String target,
                                  java.lang.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.

Throws:

XPathException - if an error occurs

getAssociatedStylesheets

public javax.xml.transform.Source[] getAssociatedStylesheets()
                                                      throws javax.xml.transform.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

javax.xml.transform.TransformerException
