Revision Content

A processing instruction provides an opportunity for application-specific instructions to be embedded within XML and which can be ignored by XML processors which do not support processing their instructions (outside of their having a place in the DOM).

A Processing instruction is distinct from a XML Declaration which is used for other information about the document such as encoding and which appear (if it does) as the first item in the document.

User-defined processing instructions cannot begin with 'xml', as these are reserved (e.g., as used in <?xml-stylesheet ?>).

Attributes

  • target (DOMString) - after the <? and before whitespace delimiting it from data
  • data (DOMString) - first non-whitespace character after target and before ?>

Specification

  • https://www.w3.org/TR/REC-DOM-Level-1/level-one-core.html#ID-1004215813
