Class ProcessingInstructionImpl

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.

Since: PR-DOM-Level-1-19980818.

Method Detail

getBaseURI

public String 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.

Returns: The absolute base URI of this node or null.

Since: DOM Level 3

getData

public String getData()
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

getNodeName

public String getNodeName()
Returns the target

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.

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 " In HTML, target is always null.

Note that getNodeName is aliased to getTarget.

setData

public void setData(String data)
Change the data content of this PI. Note that setData is aliased to setNodeValue.

Throws: DOMException(NO_MODIFICATION_ALLOWED_ERR) if node is read-only.
