Without this, it only encodes the bare + minimum. +* `disable_html_ns` (boolean): Prevents the parser from automatically + assigning the HTML5 namespace to the DOM document. This is for + non-namespace aware DOM tools. +* `target_document` (\DOMDocument): A DOM document that will be used as the + destination for the parsed nodes. +* `implicit_namespaces` (array): An assoc array of namespaces that should be + used by the parser. Name is tag prefix, value is NS URI. + +## The Low-Level API + +This library provides the following low-level APIs that you can use to +create more customized HTML5 tools: + +- A SAX-like event-based parser that you can hook into for special kinds +of parsing. +- A flexible error-reporting mechanism that can be tuned to document +syntax checking. +- A DOM implementation that uses PHP's built-in DOM library. + +The unit tests exercise each piece of the API, and every public function +is well-documented. + +### Parser Design + +The parser is designed as follows: + +- The `Scanner` handles scanning on behalf of the parser. +- The `Tokenizer` requests data off of the scanner, parses it, clasifies +it, and sends it to an `EventHandler`. It is a *recursive descent parser.* +- The `EventHandler` receives notifications and data for each specific +semantic event that occurs during tokenization. +- The `DOMBuilder` is an `EventHandler` that listens for tokenizing +events and builds a document tree (`DOMDocument`) based on the events. + +### Serializer Design + +The serializer takes a data structure (the `DOMDocument`) and transforms +it into a character representation -- an HTML5 document. + +The serializer is broken into three parts: + +- The `OutputRules` contain the rules to turn DOM elements into strings. The +rules are an implementation of the interface `RulesInterface` allowing for +different rule sets to be used. +- The `Traverser`, which is a special-purpose tree walker. It visits +each node node in the tree and uses the `OutputRules` to transform the node +into a string. +- `HTML5` manages the `Traverser` and stores the resultant data +in the correct place. + +The serializer (`save()`, `saveHTML()`) follows the +[section 8.9 of the HTML 5.0 spec](http://www.w3.org/TR/2012/CR-html5-20121217/syntax.html#serializing-html-fragments). +So tags are serialized according to these rules: + +- A tag with children: <foo>CHILDREN</foo> +- A tag that cannot have content: <foo> (no closing tag) +- A tag that could have content, but doesn't: <foo></foo> + +## Known Issues (Or, Things We Designed Against the Spec) + +Please check the issue queue for a full list, but the following are +issues known issues that are not presently on the roadmap: + +- Namespaces: HTML5 only [supports a selected list of namespaces](http://www.w3.org/TR/html5/infrastructure.html#namespaces) + and they do not operate in the same way as XML namespaces. A `:` has no special + meaning. + By default the parser does not support XML style namespaces via `:`; + to enable the XML namespaces see the [XML Namespaces section](#xml-namespaces) +- Scripts: This parser does not contain a JavaScript or a CSS + interpreter. While one may be supplied, not all features will be + supported. +- Rentrance: The current parser is not re-entrant. (Thus you can't pause + the parser to modify the HTML string mid-parse.) +- Validation: The current tree builder is **not** a validating parser. + While it will correct some HTML, it does not check that the HTML + conforms to the standard. (Should you wish, you can build a validating + parser by extending DOMTree or building your own EventHandler + implementation.) + * There is limited support for insertion modes. + * Some autocorrection is done automatically. + * Per the spec, many legacy tags are admitted and correctly handled, + even though they are technically not part of HTML5. +- Attribute names and values: Due to the implementation details of the + PHP implementation of DOM, attribute names that do not follow the + XML 1.0 standard are not inserted into the DOM. (Effectively, they + are ignored.) If you've got a clever fix for this, jump in! +- Processor Instructions: The HTML5 spec does not allow processor + instructions. We do. Since this is a server-side library, we think + this is useful. And that means, dear reader, that in some cases you + can parse the HTML from a mixed PHP/HTML document. This, however, + is an incidental feature, not a core feature. +- HTML manifests: Unsupported. +- PLAINTEXT: Unsupported. +- Adoption Agency Algorithm: Not yet implemented. (8.2.5.4.7) + +## XML Namespaces + +To use XML style namespaces you have to configure well the main `HTML5` instance. + +```php +use Masterminds\HTML5; +$html = new HTML5(array( + "xmlNamespaces" => true +)); + +$dom = $html->loadHTML('<t:tag xmlns:t="http://www.example.com"/>'); + +$dom->documentElement->namespaceURI; // http://www.example.com + +``` + +You can also add some default prefixes that will not require the namespace declaration, +but its elements will be namespaced. + +```php +use Masterminds\HTML5; +$html = new HTML5(array( + "implicitNamespaces"=>array( + "t"=>"http://www.example.com" + ) +)); + +$dom = $html->loadHTML('<t:tag/>'); + +$dom->documentElement->namespaceURI; // http://www.example.com + +``` + +## Thanks to... + +The dedicated (and patient) contributors of patches small and large, +who have already made this library better.See the CREDITS file for +a list of contributors. + +We owe a huge debt of gratitude to the original authors of html5lib. + +While not much of the original parser remains, we learned a lot from +reading the html5lib library.
