public class PIGrabber
extends ProxyReceiver

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

PIGrabber

public PIGrabber(Receiver next)

Method Details

setFactory

public void setFactory(Configuration config)

setCriteria

public void setCriteria(String media,
 String title)

Define the matching criteria

Parameters:

media - the required media. Note that Saxon does not implement the complex CSS3-based syntax for media queries. By default, the media value is simply ignored. An algorithm for comparing the requested media with the declared media can be defined using the method Configuration.setMediaQueryEvaluator(Comparator).

title - the required title

setBaseURI

public void setBaseURI(String uri)

Set the base URI

Parameters:

uri - the base URI

setResourceResolver

public void setResourceResolver(ResourceResolver resolver)

Set the URI resolver to be used for the href attribute

Parameters:

resolver - the URI resolver

startElement

public void startElement(NodeName elemName,
 SchemaType type,
 AttributeMap attributes,
 NamespaceMap namespaces,
 Location location,
 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:

elemName - the name of the element.

type - the type annotation of the element.

attributes - the attributes of this element

namespaces - the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elements

location - an object providing information about the module, line, and column where the node originated

properties - bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in class ReceiverOption

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(String target,
 UnicodeString data,
 Location 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 - provides information such as line number and system ID.

properties - Additional information about the PI.

Throws:

XPathException - if an error occurs

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
