Pass file handle in XMLReader

Hi internals The XMLReader object only allows a file name in the constructor and the open() method. While this is OK most of the time, files stored at cloud services not accessible via an URL must be downloaded first. For big files (e.g 100MB to 1GB and more), this requires a lot of time and resources. If the XMLReader would be able accept a file handle too, we could pass the handle of a stream to the methods and the XMLReader could process the XML data on the fly without the need of a local copy. Is it possible to allow a file handle in the existing methods or is a new one required due to type or other constraints like implementation difficulties? The open() method is implemented here: https://github.com/php/php-src/blob/faea5ab837ab6393c8821f85cf8abe2723593e8e/ext/xmlreader/php_xmlreader.c#L835-L887 Not sure where the constructor is implemented. Thanks Norbert
