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.

See also the Document Object Model (DOM) Level 3 Core Specification.

public interface ProcessingInstruction extends Node {
    
The target of this processing instruction. XML defines this as being the first token following the markup that begins the processing instruction.
    public String getTarget();

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

Throws:
org.w3c.dom.DOMException NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
    public void setData(String data)
                                   throws DOMException;
