Sorry, but I don't understand the use case.

if you have this code :
    \<img src="..." alt="">

you can find
    $this->assertCount(1, $crawler->filter('img[alt=""]'));

Then, can you change the unit test with the real use case?

[2.0][HttpFoundation] Docblock for Request::isXmlHttpRequest()

Replacement for #6444.
