Passing xpath to XmlStructure::matchElement() always throws Exception

Lee src/Util/XmlStructure.php y la ruta de grabTextContentFrom() del módulo SOAP, y después crea una prueba unitaria que reproduzca un XPath como /example. La tarea está terminada cuando el XPath ya no provoca una excepción de selector CSS y se devuelve el elemento coincidente.

The signature allows param $cssOrXpath: https://github.com/Codeception/lib-xml/blob/main/src/Util/XmlStructure.php#L37
But when an xpath is passed, it will throw an exception.

This is broken since Codeception 5.0:

• v4 used to catch parser exceptions, and then continues to try an xpath: https://github.com/Codeception/Codeception/blob/4.2.2/src/Codeception/Util/XmlStructure.php#L39-L46
• v5 does not: https://github.com/Codeception/lib-xml/blob/main/src/Util/XmlStructure.php#L40

Reproduce

• Create a unit test and pass an xpath, for example through Codeceptions SOAP module grabTextContentFrom() (https://codeception.com/docs/modules/SOAP#grabTextContentFrom):

$xpath = '/example';
$I->grabTextContentFrom($xpath))

• Run the test. Output:

1) ExampleCest: Call undefined operation
 Test  ExampleCest.php:example

  [Symfony\Component\CssSelector\Exception\SyntaxErrorException] Expected selector, but <delimiter "/" at 0> found.

Scenario Steps:

 4. $I->grabTextContentFrom("/example") at (..)

Possible fix

Re-implement the try-catch:

    public function matchElement(string $cssOrXPath): ?DOMNode
    {
        $domXpath = new DOMXpath($this->xml);
        try {
            $selector = (new CssSelectorConverter())->toXPath($cssOrXPath);
            $els = $domXpath->query($selector);
            if ($els !== false && count($els) > 0) {
                return $els->item(0);
            }
        } catch (\Symfony\Component\CssSelector\Exception\ParseException $e) {
        }
        $els = $domXpath->query($cssOrXPath);
        if ($els !== false && count($els) > 0) {
            return $els->item(0);
        }
        throw new ElementNotFound($cssOrXPath);
    }
