The ProcessingInstruction
interface represents a processing instruction; that is, a Node
which embeds an instruction targeting a specific application but that can be ignored by any other applications which don't recognize the instruction.
A processing instruction is different from the XML declaration.
User-defined processing instructions cannot begin with "xml
", as xml
-prefixed processing-instruction target names are reserved by the XML specification for particular, standard uses (see, for example, <?xml-stylesheet ?>
).
The ProcessingInstruction
interface inherits methods and properties from Node
.
