If you want to read a file, with XML extension, it's possible. It's also possible to read a file with OINFNDW extension if you want.
PHP Code:
new iFile = fopen( "MyFile.MyExtension", "r" ), iReadRows, cMyRow[ 256 ][ 32 ];
while( !feof( iFile ) ) fgets( iFile, cMyRow[ iReadRows ], 31 ), iReadRows++;
fclose( iFile );
Be careful, a file which not exists and it's opened will crash server.
