CSSContentParser
class CSSContentParser (View source)
CSSContentParser enables parsing & assertion running of HTML content via CSS selectors.
It works by converting the content to XHTML using tidy, rewriting the CSS selectors as XPath queries, and executing those using SimpeXML.
It was built to facilitate testing using PHPUnit and contains a number of assert methods that will throw PHPUnit assertion exception when applicable.
Tries to use the PHP tidy extension (http://php.net/tidy), and falls back to the "tidy" CLI tool. If none of those exists, the string is parsed directly without sanitization.
Caution: Doesn't fully support HTML elements like
Traits

Provides extensions to this object to integrate it with standard config API methods.

Methods
An implementation of the factory method, allows you to create an instance of a class
Creates a class instance by the "singleton" design pattern.
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
Gets the uninherited value for the given config option
Returns a number of SimpleXML elements that match the given CSS selector.
Allows querying the content through XPATH selectors.
Converts a CSS selector into an equivalent xpath expression.

create(mixed ...$args)
An implementation of the factory method, allows you to create an instance of a class
This method will defer class substitution to the Injector API, which can be customised via the Config API to declare substitution classes.
This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create(SiteTree::class); $list = SiteTree::get();
static Injectable
singleton(string $class = null)
Creates a class instance by the "singleton" design pattern.
It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).
static Config_ForClass
config()
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
mixed
uninherited(string $name)
Gets the uninherited value for the given config option
__construct($content)

SimpleXMLElement[]
getBySelector(string $selector)
Returns a number of SimpleXML elements that match the given CSS selector.
Currently the selector engine only supports querying by tag, id, and class. See getByXpath() for a more direct selector syntax.

getByXpath(string $xpath)
Allows querying the content through XPATH selectors.

selector2xpath(string $selector)
