Class ProcessingInstructionImpl

org.htmlunit.cyberneko.xerces.dom.NodeImpl

All Implemented Interfaces:

Cloneable, EventTarget, Node, NodeList, ProcessingInstruction

public class ProcessingInstructionImpl
extends CharacterDataImpl
implements ProcessingInstruction

Processing Instructions (PIs) permit documents to carry processor-specific information alongside their actual content. PIs are most common in XML, but they are supported in HTML as well.

This class inherits from CharacterDataImpl to reuse its setNodeValue method.

Method Details

getNodeType

public short getNodeType()

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. 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.

getNodeType in interface Node

Specified by:

getNodeType in class NodeImpl

getNodeName

public String getNodeName()

the name of this node. Returns the target

Specified by:

getNodeName in interface Node

Specified by:

getNodeName in class NodeImpl

getTarget

public String getTarget()

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 "<?" token that begins the PI.

In HTML, target is always null.

Note that getNodeName is aliased to getTarget.

Specified by:

getTarget in interface ProcessingInstruction

getBaseURI

public String getBaseURI()

The absolute base URI of this node or null if undefined. This value is computed according to . However, when the Document supports the feature "HTML" , the base URI is computed using first the value of the href attribute of the HTML BASE element if any, and the value of the documentURI attribute from the Document interface otherwise.
When the node is an Element, a Document or a a ProcessingInstruction, this attribute represents the properties [base URI] defined in . When the node is a Notation, an Entity, or an EntityReference, this attribute represents the properties [declaration base URI] in the . How will this be affected by resolution of relative namespace URIs issue?It's not.Should this only be on Document, Element, ProcessingInstruction, Entity, and Notation nodes, according to the infoset? If not, what is it equal to on other nodes? Null? An empty string? I think it should be the parent's.No.Should this be read-only and computed or and actual read-write attribute?Read-only and computed (F2F 19 Jun 2000 and teleconference 30 May 2001).If the base HTML element is not yet attached to a document, does the insert change the Document.baseURI? Yes. (F2F 26 Sep 2001) 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.

Specified by:

getBaseURI in interface Node

Overrides:

getBaseURI in class NodeImpl

Returns:

The absolute base URI of this node or null.
