PIGrabber

java.lang.Object
- net.sf.saxon.event.SequenceReceiver
- - net.sf.saxon.event.ProxyReceiver
  - - net.sf.saxon.event.PIGrabber

All Implemented Interfaces:

javax.xml.transform.Result, Receiver
```
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

    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,

                  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(java.lang.String target,
                                  java.lang.CharSequence data,
                                  int locationId,

```
    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:

  - getAssociatedStylesheets
```
public javax.xml.transform.Source[] getAssociatedStylesheets()
