DOMDocument::load — Load XML from a file
Loads an XML document from a file.
Unix style paths with forward slashes can cause significant performance degradation on Windows systems; be sure to call realpath() in such a case.
filenameThe path to the XML document.
optionsBitwise OR of the libxml option constants.
   Restituisce TRUE in caso di successo, FALSE in caso di fallimento.  If called statically, returns a
   DOMDocument o FALSE in caso di fallimento.
  
   If an empty string is passed as the filename
   or an empty file is named, a warning will be generated. This warning
   is not generated by libxml and cannot be handled using libxml's error
   handling functions.
  
Questo metodo può essere chiamato in modo statico, ma genererà un errore E_STRICT.
