Example
var pubid = document.doctype.publicId;The
example above saves a reference to the publicId of the
doctype. So if we were on a page with an XHTML 1.0 Strict doctype, the
pubid variable would have the value
-//W3C//DTD XHTML 1.0 Strict//EN.
Description
The public identifier of an
Entity, or null if no public
identifier is specified.
This property is read-only.

| Partial | Partial | Partial | Full | Full | Full | None | None | Full | Full | Full |
Only Opera in XHTML mode or
XML1
and Internet Explorer in XML are able to
retrieve the publicId of an Entity or Notation, because those
are the only environments in which the root objects themselves are exposed
(see Entity and Notation for
details).
