Alpine 3.21+ & newer libxml trows "Document is empty" errors when trying to unserialize empty body #9

Description

Hi,

We're running our application in an alpine versioned container with PHP 8.4 and we found a found a bug regarding new SimpleXmlElement() with an empty body.

The new versions will trigger an libxml error which wasn't there before.

It gives us the "Document is empty" error which is totally true and valid.
But maybe you should check the response before putting it in SimpleXml.

We do get this when we run a file-exists check. Which results in a 404 response, but the response shouldn't go through SimpleXmlElement() then.

Regards, Bert
