这是调用webservice服务接口返回的数据不知道怎么解析，有哪位大神能帮忙解决一下。

需要实现NSXMLParserDelegate协议。
头文件：
#import <UIKit/UIKit.h>@interface BIDViewController : UIViewController <NSXMLParserDelegate>
{
    NSURLConnection *theConnection;
    NSMutableData *webData;
    NSXMLParser *xmlParser;
    NSMutableString *soapResults;
    
    BOOL recordResults;
}
- (IBAction)RequestZoneTime:(UIButton *)sender;
@property (strong, nonatomic) IBOutlet UILabel *requestTime;
@end.m文件：#import "BIDViewController.h"@interface BIDViewController ()@end@implementation BIDViewController
@synthesize requestTime;- (void)viewDidLoad
{
    [super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}- (IBAction)RequestZoneTime:(UIButton *)sender
{
    NSString *soapMessage = [NSString stringWithFormat:
             @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
             "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
             "<soap:Body>\n"
             "<LocalTimeByZipCode xmlns=\"http://www.ripedev.com/\">"
             "<ZipCode>12345</ZipCode>\n"
             "</LocalTimeByZipCode>\n"
             "</soap:Body>\n"
             "</soap:Envelope>\n"];
    
    NSString *address =@"http://www.ripedevelopment.com/webservices/LocalTime.asmx";
    NSURL* url = [NSURL URLWithString:address];
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
    
    [theRequest addValue: @"text/xml; charset=utf-8"forHTTPHeaderField:@"Content-Type"];
    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
    [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
    
    [theRequest addValue: @"http://www.ripedev.com/LocalTimeByZipCode"forHTTPHeaderField:@"SOAPAction"];
    [theRequest setHTTPMethod:@"POST"];
    [theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
    
     theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
    if(theConnection)
    {
        webData = [NSMutableData data];
    }
    else
    {
        NSLog(@"theConnection is NULL");
    }
    
    [theConnection scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSRunLoopCommonModes];
}-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    [webData setLength: 0];
    NSLog(@"connection: didReceiveResponse:1");
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    [webData appendData:data];
    NSLog(@"connection: didReceiveData:2");
}-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
    NSLog(@"ERROR with theConenction");
}-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSLog(@"3 DONE. Received Bytes: %d", [webData length]);
    NSString *theXML = [[NSString alloc] initWithBytes:[webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding];
    NSLog(@"received data=%@", theXML);
    
    xmlParser = [[NSXMLParser alloc] initWithData:webData];
    [xmlParser setDelegate: self];
    [xmlParser setShouldResolveExternalEntities:YES];
    [xmlParser parse];
}-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI
                qualifiedName:(NSString *)qName attributes: (NSDictionary *)attributeDict
{
    NSLog(@"4 parser didStarElemen: namespaceURI: attributes:%@", elementName);
    
    if( [elementName isEqualToString:@"LocalTimeByZipCodeResult"])
    {
        if(!soapResults)
        {
            soapResults = [[NSMutableString alloc] init];
        }
        recordResults =YES;
    }
}-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
    NSLog(@"5 parser: foundCharacters:");
    if(recordResults)
    {
        [soapResults appendString: string];
    }
}-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
            namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
    NSLog(@"6 parser: didEndElement:");
    
    if( [elementName isEqualToString: @"LocalTimeByZipCodeResult"])
    {
        recordResults =FALSE;
        NSLog(@"receivedResult timezone=%@",soapResults);
    
        requestTime.text = soapResults;        NSLog(@"hoursOffset result");
    }
}- (void)parserDidStartDocument:(NSXMLParser *)parser
{
    NSLog(@"-------------------start--------------");
}- (void)parserDidEndDocument:(NSXMLParser *)parser
{
    NSLog(@"-------------------end--------------");
}
@end看懂了上面的代码就没有问题了。

实现这个协议还是不能解析，处理带MTOM附件的SOAP消息好像是跟一般的soap消息是不同的，他返回的数据是带分隔符的------=_Part_42_12403951.1406169795632

我就是不知道怎么去处理这些分隔符，就是这个参数boundary
