Translate CSS selectors to XPath queries.
=========================================

A lightweight and dependency free CSS to XPath translator. This repository is used to bring modern DOM functionality like [`querySelectorAll()`][qsa] to PHP in the [PHP.Gt/Dom][gt-dom] project.

Example usage
-------------


```php
use Gt\CssXPath\Translator;

$html = <<<HTML
<form>
	<label>
		Name
		<input name="name" />
	</label>
	<label>
		Code:
		<input name="code" />
	</label>
	<button name="do" value="submit">Submit code</button>
</form>
HTML;

$document = new DOMDocument();
$document->loadHTML($html);

$xpath = new DOMXPath($document);
$inputElementList = $xpath->query(new Translator("form>label>input"));
```

## Using this library with XML Documents

To correctly work with XML documents, where the attributes are case-sensitive, pass `false` to the `htmlMode` property of the constructor.

```php
$translator = new Translator("[data-FOO='bar']", htmlMode: false);
```

It's perhaps worth noting that for XML-style matching to work, you must load the document content with DOMDocument->load/DOMDocument->loadXML instead of DOMDocument->loadHTMLFile/DOMDocument->loadHTML, as the HTML loading methods automatically convert the tags and attribute names to lowercase. This is handled automatically when using [PHP.Gt/Dom][gt-dom].
