First create an instance of the validator: ``` $dtv = new Doctype_Validator(); ``` 2. Assign the doctype you want to validate: ``` $doctype = ""; ``` ### Is it a valid doctype? [](#is-it-a-valid-doctype) Checking to see if a doctype is valid. ``` $valid = $dtv->validate($doctype)->isValid(); ``` *@return boolean TRUE or FALSE.* ### Does it match an official doctype? [](#does-it-match-an-official-doctype) A check can be performed with `isMatch()` to see if there is a match. ``` $match = $dtv->validate($doctype)->isMatch(); ``` *@return boolean TRUE or FALSE* ``` $matches = $dtv->validate($doctype)->matches(); ``` *@return string of name of match, or NULL if no match.* ### Errors [](#errors) If a doctype is not valid, `Doctype_Validator` will try to analyse why it is not valid. A list of errors can be found in `Doctype_Error.php`. A simple check if a doctype has errors in it can be performed by the `hasError()` function. ``` $error = $dtv->validate($doctype)->hasError(); ``` *@return boolean TRUE or FALSE.* You can retrieve errors with the `getErrors()` method. ``` $result = $dtv->validate($doctype); if($result->hasErrors()) { $errors = $result->getErrors(); } ``` *@return array of errors.* ### Fragments [](#fragments) The doctype will be dissected into smaller fragments and these can be access with `getFragments()`. ``` $fragments = $dtv->validate($doctype)->getFragments(); ``` *@return array of fragmentens* License ------- [](#license) Doctype Validator is licensed under the MIT License - see the `LICENSE` file for details Author ------ [](#author) Jarne W.
