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.

public short getNodeType()
getNodeType in interface org.w3c.dom.NodegetNodeType in class NodeImplpublic java.lang.String getNodeName()
getNodeName in interface org.w3c.dom.NodegetNodeName in class NodeImplpublic java.lang.String getTarget()
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.
getTarget in interface org.w3c.dom.ProcessingInstructionpublic java.lang.String getData()
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

the stored data may exceed the permitted length of strings. If so,
getData() will throw this DOMException advising the user to
instead retrieve the data in chunks via the substring() operation.public void setData(java.lang.String data)
