    String target,
    String data) 
{
    //
    // Constructors
    //
        super(ownerDoc, data);
        this.target = target;

Factory constructor.

 public String getBaseURI() 
{
        if (needsSyncData()) {
            synchronizeData();
        }
        return ownerNode.getBaseURI();
}

Returns the absolute base URI of this node or null if the implementation wasn't able to obtain an absolute URI. Note: If the URI is malformed, a null is returned.

 public String getData() 
{
        if (needsSyncData()) {
            synchronizeData();
        }
        return data;
}

A PI's data content tells the processor what we actually want it to do. It is defined slightly differently in HTML and XML.

In XML, the data begins with the non-whitespace character immediately after the target -- @see getTarget().

In HTML, the data begins with the character immediately after the "<?" token that begins the PI.

Note that getNodeValue is aliased to getData

 public String getNodeName() 
{
        if (needsSyncData()) {
            synchronizeData();
        }
        return target;
}

Returns the target

 public short getNodeType() 
{
        return Node.PROCESSING_INSTRUCTION_NODE;
}

A short integer indicating what type of node this is. The named constants for this value are defined in the org.w3c.dom.Node interface.

 public String getTarget() 
{
        if (needsSyncData()) {
            synchronizeData();
        }
        return target;
}

A PI's "target" states what processor channel the PI's data should be directed to. It is defined differently in HTML and XML.

In XML, a PI's "target" is the first (whitespace-delimited) token following the " In HTML, target is always null.

Note that getNodeName is aliased to getTarget.

 public  void setData(String data) 
{
        // Hand off to setNodeValue for code-reuse reasons (mutation
        // events, readonly protection, synchronizing, etc.)
        setNodeValue(data);
}

Change the data content of this PI. Note that setData is aliased to setNodeValue.
