Hii

I need to call a XML file from a WCF Service and Parse the content of XML in iPhone.
I m able to call the service url but when doing parsing using NSXMLParser I couldn't get a patricular attribute value in XML .I m using a ViewController application in XCode.

My XML file is like this :

<GetCompanyResponse xmlns="http://schemas.datacontract.org/2004/07/DomainModel" xmlns:i="http://www.w3.org/2001/XMLSchema-
<CompanyList>
  <Company>
     <Id>b9ca2e32-ce88-4d72-99ce-9bc592511e85</Id>
  </Company>
</CompanyList>

I have tried this code :

NSString *urlString = [NSString stringWithFormat:@"http://192.168.0.107:8732/Design_Time_Addresses/IServices/
AppointmentService/json/GetCompany";
NSURL *jsonUrl =[NSURL URLWithString:urlString];

 NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL:jsonUrl];
    [parser setDelegate:self];
    [parser setShouldProcessNamespaces:NO];
    [parser setShouldReportNamespacePrefixes:NO];
    [parser setShouldResolveExternalEntities:NO];
    
    [parser parse];
    [parser release];  

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName 
  namespaceURI:(NSString *)namespaceURI qualifiedName:
(NSString *)qName attributes:(NSDictionary *)attributeDict
{
        
    if ([elementName isEqualToString:@"Company"]) {
        NSString *name=[attributeDict objectForKey:@"Id"];
      
    }
}

But when I check for the value in 'name' it is returning nil.Couldn't get where I m I going wrong?What should I change?How can I get the value in ID attribute?

Any help would be appreciated..

Thanks in advance..
