Question

Entering Doctypes

Answer 1

A:

Are users allowed to enter a custom doctype?

Perhaps create a base class

Doc

And extend it to each type, ex:

StrictDoc extends Doc etc.

And it'll set its own doc type for each. If you want to add to the doc types, simply create another class that extends Doc.

Answer 2

+1 A:

I think you should just checkout the doctype w3c list. http://www.w3.org/QA/2002/04/valid-dtd-list.html

Answer 3

+1 A:

It depends if you want to allow entering custom doctypes. If you consider that situation an exception you should probably throw an exception when someone tries using undefined doctype. You could also provide a method for defining a custom doctype and force using that method before setting the actual doctype.

I would do something like this:

class Document {
    private $doctypes = array(
        'html4' => '...',
        'xhtml1strict' => '...'
    );

    private $doctype = null;

    public function addCustomDocType($name, $definition) {
        if (empty($this->doctypes[$name])) {
            $this->doctypes[$name] = $definition;
        } else {
            throw new Exception('Definition already exists');
        }
    }

    public function setDocType($name) {
        if (!empty($this->doctypes[$name])) {
            $this->doctype = $this->doctypes[$name];
        } else {
            throw new Exception('Doctype not found');
        }
    }
}

The second solution where you must type doctype definition is IMO ugly and I would avoid it.

Exactly what I was looking for.
