Question

I am reading a xml file with:

$reader = new XMLReader();
$reader->xml($myXml, NULL, LIBXML_NOWARNIG | LIBXML_NOERROR);

but in the same situation in any occasion show this warning on the line $reader->xml($myXml, NULL, LIBXML_NOWARNING, LIBXML_NOERROR);

warning: XMLReader::XML() [xmlreader.xml] Empty string supplied as input.

My question is, Why is showing the warning whether I have used the option LIBXML_NOWARNIG.

Thank you very much.

Answer 1

you are missing the N in WARNING.

Also, it should be new not nex and the method signature of XMLReader::url is

bool XMLReader::xml ( string $source [, string $encoding [, int $options = 0 ]] )

which means you should call it

$reader->xml($myXml, NULL, LIBXML_NOWARNING|LIBXML_NOERROR);

However: both constants suppress parsing errors and passing an empty string to the method is not a parsing error but a logic error (you cannot parse an empty string) and thus, you cannot suppress it with them.
