Example
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"
[
<!ATTLIST input validate CDATA #IMPLIED>
<!ATTLIST input range CDATA #IMPLIED>
]>
The example above shows an XHTML doctype with additional custom attributes,
defined as an internal subset to the main DTD.
So to retrieve and
store the contents of that internal subset (everything between, but not
including, the starting [ and ending
]), we could do this:
var subset = document.doctype.internalSubset;The text that comes back is a simple string, not a collection of nodes.
Description
A string containing the text of a DTD's internal subset.
This property is readonly.
