Question

我正在创建一个IOS应用程序。我必须使用SOAP Web服务来获取一些细节。所以我用SUDZ-C来生成存根。我可以调用Web服务并获得响应。但我无法解析回应。以下是XML响应。

LibXML2包含在Cocoa中。

您可以使用NSXMLParser类来解析它。使用它可以解析的委托方法。我发布我的尝试来解析你的xml.It没有完成。我给你一个解析的基本代码。你必须做其余的事情。这里＆＃34; xmlInput＆＃34;是带有xmlstring的NSString类型。

    NSData* xmlData = [xmlInput dataUsingEncoding:NSUTF8StringEncoding];

    NSXMLParser  * xmlParser = [[NSXMLParser alloc] initWithData:[xmlData copy]];
    [xmlParser setDelegate:(id)self];
    [xmlParser setShouldResolveExternalEntities: YES];
    [xmlParser parse];

创建一个xmlparser对象并输入你的xmlData.Set其委托。

     //this delegate calls when parsing start.Only once.
    - (void)parserDidStartDocument:(NSXMLParser *)parser
    {
           recordResults = NO;//declared in .h
           MonthFlag = NO;//declared in .h
           TaskFlag = NO;//declared in .h
           Arry = nil;//declared in .h
    }

   // This delgate calls when each tag name is found.
  -(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName  namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName
                attributes: (NSDictionary *)attributeDict
          {
            strElementName =  [elementName copy];//strElementName is declared in .h

                NSLog(@"%@",strElementName);
               if([elementName isEqualToString:@"monthListItem"]){
                  MonthFlag = YES;
               }
               if([elementName isEqualToString:@"taskListItem"]){
                 TaskFlag = YES;
               }
              strElementValue = @""; //strElementValue is declared in .h
          }


 //This is called when each tag value is found.
 -(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
 {
        strElementValue = [NSString stringWithFormat:@"%@%@", strElementValue,[string copy]];
        NSLog(@"%@",strElementValue);
       //NSLog(@"%@ : %@",strElmentName,strElementValue);
       recordResults=(strElementValue.length > 0);
  }

  // This deleagte will call in the end of each tag name.
    -(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI: (NSString *)namespaceURI qualifiedName:(NSString *)qName
  {
           NSLog(@"%@ - %@",elementName,strElementValue);
           if (recordResults) {
             if (MonthFlag) {
                if(dicTemp==nil){
                   dicTemp = [[NSMutableDictionary alloc] init];
                for (int i=0; i<10; i++) {
                  [dicTemp setObject:@"" forKey:strElementName];
                }
              }
            [dicTemp setObject:strElementValue forKey:elementName ];
          }
             }     
              if(([elementName isEqualToString:@"monthListItem"] ) && dicTemp!=nil) {
                   if(Arry==nil)Arry = [[NSMutableArray alloc] init];
                       [Arry addObject:[dicTemp copy]];
                   dicTemp = nil;
                   [dicTemp release];
                   MonthFlag = NO;
                  NSLog(@"arry test %@",[Arry description]);
               }
      }

       // This delegate will call when parsing finishes . only once
       - (void)parserDidEndDocument:(NSXMLParser *)parser
       {
           recordResults = NO;
       }
