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. +- Reentrance: 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 = $html->loadHTML(''); + +$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 = $html->loadHTML(''); + +$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.

Allows extraction of CSS files into a data structure, manipulation of said structure and output as (optimized) CSS. + +## Usage + +### Installation using Composer + +```bash +composer require sabberworm/php-css-parser +``` + +### Extraction + +To use the CSS Parser, create a new instance. The constructor takes the following form: + +```php +new \Sabberworm\CSS\Parser($css); +``` + +To read a file, for example, you’d do the following: + +```php +$parser = new \Sabberworm\CSS\Parser(file_get_contents('somefile.css')); +$cssDocument = $parser->parse(); +``` + +The resulting CSS document structure can be manipulated prior to being output. + +### Options + +#### Charset + +The charset option will only be used if the CSS file does not contain an `@charset` declaration. UTF-8 is the default, so you won’t have to create a settings object at all if you don’t intend to change that. + +```php +$settings = \Sabberworm\CSS\Settings::create() + ->withDefaultCharset('windows-1252'); +$parser = new \Sabberworm\CSS\Parser($css, $settings); +``` + +#### Strict parsing + +To have the parser throw an exception when encountering invalid/unknown constructs (as opposed to trying to ignore them and carry on parsing), supply a thusly configured `\Sabberworm\CSS\Settings` object: + +```php +$parser = new \Sabberworm\CSS\Parser( + file_get_contents('somefile.css'), + \Sabberworm\CSS\Settings::create()->beStrict() +); +``` + +Note that this will also disable a workaround for parsing the unquoted variant of the legacy IE-specific `filter` rule. + +#### Disable multibyte functions + +To achieve faster parsing, you can choose to have PHP-CSS-Parser use regular string functions instead of `mb_*` functions. This should work fine in most cases, even for UTF-8 files, as all the multibyte characters are in string literals. Still it’s not recommended using this with input you have no control over as it’s not thoroughly covered by test cases. + +```php +$settings = \Sabberworm\CSS\Settings::create()->withMultibyteSupport(false); +$parser = new \Sabberworm\CSS\Parser($css, $settings); +``` + +### Manipulation + +The resulting data structure consists mainly of five basic types: `CSSList`, `RuleSet`, `Rule`, `Selector` and `Value`. There are two additional types used: `Import` and `Charset`, which you won’t use often. + +#### CSSList + +`CSSList` represents a generic CSS container, most likely containing declaration blocks (rule sets with a selector), but it may also contain at-rules, charset declarations, etc. + +To access the items stored in a `CSSList` – like the document you got back when calling `$parser->parse()` –, use `getContents()`, then iterate over that collection and use `instanceof` to check whether you’re dealing with another `CSSList`, a `RuleSet`, a `Import` or a `Charset`. + +To append a new item (selector, media query, etc.) to an existing `CSSList`, construct it using the constructor for this class and use the `append($oItem)` method. + +#### RuleSet + +`RuleSet` is a container for individual rules. The most common form of a rule set is one constrained by a selector. The following concrete subtypes exist: + +* `AtRuleSet` – for generic at-rules for generic at-rules which are not covered by specific classes, i.e., not `@import`, `@charset` or `@media`. A common example for this is `@font-face`. +* `DeclarationBlock` – a `RuleSet` constrained by a `Selector`; contains an array of selector objects (comma-separated in the CSS) as well as the rules to be applied to the matching elements. + +Note: A `CSSList` can contain other `CSSList`s (and `Import`s as well as a `Charset`), while a `RuleSet` can only contain `Rule`s. + +If you want to manipulate a `RuleSet`, use the methods `addRule(Rule $rule)`, `getRules()` and `removeRule($rule)` (which accepts either a `Rule` or a rule name; optionally suffixed by a dash to remove all related rules). + +#### Rule + +`Rule`s just have a string key (the rule) and a `Value`. + +#### Value + +`Value` is an abstract class that only defines the `render` method. The concrete subclasses for atomic value types are: + +* `Size` – consists of a numeric `size` value and a unit. +* `Color` – colors can be input in the form #rrggbb, #rgb or schema(val1, val2, …) but are always stored as an array of ('s' => val1, 'c' => val2, 'h' => val3, …) and output in the second form. +* `CSSString` – this is just a wrapper for quoted strings to distinguish them from keywords; always output with double quotes. +* `URL` – URLs in CSS; always output in `URL("")` notation. + +There is another abstract subclass of `Value`, `ValueList`: A `ValueList` represents a lists of `Value`s, separated by some separation character (mostly `,`, whitespace, or `/`). + +There are two types of `ValueList`s: + +* `RuleValueList` – The default type, used to represent all multivalued rules like `font: bold 12px/3 Helvetica, Verdana, sans-serif;` (where the value would be a whitespace-separated list of the primitive value `bold`, a slash-separated list and a comma-separated list). +* `CSSFunction` – A special kind of value that also contains a function name and where the values are the function’s arguments. Also handles equals-sign-separated argument lists like `filter: alpha(opacity=90);`. + +#### Convenience methods + +There are a few convenience methods on `Document` to ease finding, manipulating and deleting rules: + +* `getAllDeclarationBlocks()` – does what it says; no matter how deeply nested the selectors are. Aliased as `getAllSelectors()`. +* `getAllRuleSets()` – does what it says; no matter how deeply nested the rule sets are. +* `getAllValues()` – finds all `Value` objects inside `Rule`s. + +## To-Do + +* More convenience methods (like `selectorsWithElement($sId/Class/TagName)`, `attributesOfType($type)`, `removeAttributesOfType($type)`) +* Real multibyte support. Currently, only multibyte charsets whose first 255 code points take up only one byte and are identical with ASCII are supported (yes, UTF-8 fits this description). +* Named color support (using `Color` instead of an anonymous string literal) + +## Use cases + +### Use `Parser` to prepend an ID to all selectors + +```php +$myId = "#my_id"; +$parser = new \Sabberworm\CSS\Parser($css); +$cssDocument = $parser->parse(); +foreach ($cssDocument->getAllDeclarationBlocks() as $block) { + foreach ($block->getSelectors() as $selector) { + // Loop over all selector parts (the comma-separated strings in a + // selector) and prepend the ID. + $selector->setSelector($myId.' '.$selector->getSelector()); + } +} +``` + +### Shrink all absolute sizes to half + +```php +$parser = new \Sabberworm\CSS\Parser($css); +$cssDocument = $parser->parse(); +foreach ($cssDocument->getAllValues() as $value) { + if ($value instanceof CSSSize && !$value->isRelative()) { + $value->setSize($value->getSize() / 2); + } +} +``` + +### Remove unwanted rules + +```php +$parser = new \Sabberworm\CSS\Parser($css); +$cssDocument = $parser->parse(); +foreach($cssDocument->getAllRuleSets() as $oRuleSet) { + // Note that the added dash will make this remove all rules starting with + // `font-` (like `font-size`, `font-weight`, etc.) as well as a potential + // `font` rule. + $oRuleSet->removeRule('font-'); + $oRuleSet->removeRule('cursor'); +} +``` + +### Output + +To output the entire CSS document into a variable, just use `->render()`: + +```php +$parser = new \Sabberworm\CSS\Parser(file_get_contents('somefile.css')); +$cssDocument = $parser->parse(); +print $cssDocument->render(); +``` + +If you want to format the output, pass an instance of type `\Sabberworm\CSS\OutputFormat`: + +```php +$format = \Sabberworm\CSS\OutputFormat::create() + ->indentWithSpaces(4)->setSpaceBetweenRules("\n"); +print $cssDocument->render($format); +``` + +Or use one of the predefined formats: + +```php +print $cssDocument->render(Sabberworm\CSS\OutputFormat::createPretty()); +print $cssDocument->render(Sabberworm\CSS\OutputFormat::createCompact()); +``` + +To see what you can do with output formatting, look at the tests in `tests/OutputFormatTest.php`. + +## Examples + +### Example 1 (At-Rules) + +#### Input + +```css +@charset "utf-8"; + +@font-face { + font-family: "CrassRoots"; + src: url("../media/cr.ttf"); +} + +html, body { + font-size: 1.6em; +} + +@keyframes mymove { + from { top: 0px; } + to { top: 200px; } +} + +``` + +
