(X)HTML

In order to validate any page of HTML or XHTML you will need a doctype. This is a string of text that sits at the top of the document and tells the browser exactly what markup standard has been used to create the page.

XHTML Strict

This doctype is used in an XHTML document when you are not using any framset or depreciated tags.

The reverse of turning ASCII text into HTML is to convert HTML into ASCII. And to this end here is a little function that does this.
