Bug in NSScanner ?

[Manuel Guesdon]

Hi,

I can't understand why this fail

    NSString* str=@"( 1.3.6.1.4.1.4980.1.3.3 NAME 'oxyInetDomain' DESC 'Oxymium 
Inet Domain' SUP oxyTop AUXILIARY MUST dc MAY ( admContact $ admincontact $ 
billingContact $ cn $ domainCreationDate $ labeledURL $ mailRelayedBy $ 
managerEMail $ nic $ nichandle $ registrant $ soa $ techContact $ 
domaindescription $ oxymiumReferenceDisplay $ associatedServices $ 
associatedrootentity $ associatedmanagemententity $ associatedrootcompany $ 
associatedmanagemententityrights $ associatedrootentityrights $ 
associatedrootcompanyrights $ parkmessage $ logoURL ) )";
      NSScanner *aScanner = [NSScanner scannerWithString:str];

      if (0)     // If 1, it works !
        {
          BOOL upTo1=[aScanner scanUpToString:@"MUST "
                               intoString:NULL];
          NSLog(@"upTo1=%d",upTo1);
          if (upTo1)
            {
              BOOL scan1=[aScanner scanString:@"MUST "
                                   intoString:NULL];
              NSLog(@"scan1=%d",scan1);
              if (scan1)
                {
                  NSString* must=nil;
                  [aScanner scanUpToString:@" "
                            intoString:&must];
                }
            };
        };
      NSLog(@"scanLocation=%u",[aScanner scanLocation]);
      NSLog(@"scan=[%@]",[[aScanner string] substringFromIndex:[aScanner 
scanLocation]]);
      BOOL upTo2=[aScanner scanUpToString:@"MAY "
                          intoString:NULL];
      NSLog(@"upTo2=%d",upTo2);
      if (upTo2)
        {
          BOOL scan2=[aScanner scanString:@"MAY "
                          intoString:NULL];
          NSLog(@"scan2=%d",scan2);
        };


I try to scan str for differents components. If I scan directly up to MAY, it 
works. If I scan for must and next scan
for may, it doesn't works.
May be my code is wrong but I can't see why :-)
