ProcessingInstruction

public interface ProcessingInstruction
implements Node

org.w3c.dom.ProcessingInstruction

The ProcessingInstruction interface represents a "processing instruction", used in XML as a way to keep processor-specific information in the text of the document.

No lexical check is done on the content of a processing instruction and it is therefore possible to have the character sequence "?>" in the content, which is illegal a processing instruction per section 2.6 of [XML 1.0]. The presence of this character sequence must generate a fatal error during serialization.

`abstract Node`	`appendChild(Node newChild)` Adds the node `newChild` to the end of the list of children of this node.
`abstract Node`	`cloneNode(boolean deep)` Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes.
`abstract short`	`compareDocumentPosition(Node other)` Compares the reference node, i.e.
`abstract NamedNodeMap`	`getAttributes()` A `NamedNodeMap` containing the attributes of this node (if it is an `Element`) or `null` otherwise.
`abstract String`	`getBaseURI()` The absolute base URI of this node or `null` if the implementation wasn't able to obtain an absolute URI.
`abstract NodeList`	`getChildNodes()` A `NodeList` that contains all children of this node.
`abstract Object`	`getFeature(String feature, String version)` This method returns a specialized object which implements the specialized APIs of the specified feature and version, as specified in .
`abstract Node`	`getFirstChild()` The first child of this node.
`abstract Node`	`getLastChild()` The last child of this node.
`abstract String`	`getLocalName()` Returns the local part of the qualified name of this node.
`abstract String`	`getNamespaceURI()` The namespace URI of this node, or `null` if it is unspecified (see ).
`abstract Node`	`getNextSibling()` The node immediately following this node.
`abstract String`	`getNodeName()` The name of this node, depending on its type; see the table above.
`abstract short`	`getNodeType()` A code representing the type of the underlying object, as defined above.
`abstract String`	`getNodeValue()` The value of this node, depending on its type; see the table above.
`abstract Document`	`getOwnerDocument()` The `Document` object associated with this node.
`abstract Node`	`getParentNode()` The parent of this node.
`abstract String`	`getPrefix()` The namespace prefix of this node, or `null` if it is unspecified.
`abstract Node`	`getPreviousSibling()` The node immediately preceding this node.
`abstract String`	`getTextContent()` This attribute returns the text content of this node and its descendants.
`abstract Object`	`getUserData(String key)` Retrieves the object associated to a key on a this node.
`abstract boolean`	`hasAttributes()` Returns whether this node (if it is an element) has any attributes.
`abstract boolean`	`hasChildNodes()` Returns whether this node has any children.
`abstract Node`	`insertBefore(Node newChild, Node refChild)` Inserts the node `newChild` before the existing child node `refChild`.
`abstract boolean`	`isDefaultNamespace(String namespaceURI)` This method checks if the specified `namespaceURI` is the default namespace or not.
`abstract boolean`	`isEqualNode(Node arg)` Tests whether two nodes are equal.
`abstract boolean`	`isSameNode(Node other)` Returns whether this node is the same node as the given one.
`abstract boolean`	`isSupported(String feature, String version)` Tests whether the DOM implementation implements a specific feature and that feature is supported by this node, as specified in .
`abstract String`	`lookupNamespaceURI(String prefix)` Look up the namespace URI associated to the given prefix, starting from this node.
`abstract String`	`lookupPrefix(String namespaceURI)` Look up the prefix associated to the given namespace URI, starting from this node.
`abstract void`	`normalize()` Puts all `Text` nodes in the full depth of the sub-tree underneath this `Node`, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates `Text` nodes, i.e., there are neither adjacent `Text` nodes nor empty `Text` nodes.
`abstract Node`	`removeChild(Node oldChild)` Removes the child node indicated by `oldChild` from the list of children, and returns it.
`abstract Node`	`replaceChild(Node newChild, Node oldChild)` Replaces the child node `oldChild` with `newChild` in the list of children, and returns the `oldChild` node.
`abstract void`	`setNodeValue(String nodeValue)` The value of this node, depending on its type; see the table above.
`abstract void`	`setPrefix(String prefix)` The namespace prefix of this node, or `null` if it is unspecified.

`abstract Object`	`setUserData(String key, Object data, UserDataHandler handler)` Associate an object to a key on this node.

Public methods

getData

public abstract String getData ()

The content of this processing instruction. This is from the first non white space character after the target to the character immediately preceding the ?>.

Returns
`String`

getTarget

public abstract String getTarget ()

The target of this processing instruction. XML defines this as being the first token following the markup that begins the processing instruction.

Returns
`String`

setData

public abstract void setData (String data)

The content of this processing instruction. This is from the first non white space character after the target to the character immediately preceding the ?>.

Parameters
`data`	`String`

Throws
`DOMException`	NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
