Question

I need to call an XML file from a WCF Service and parse the content of XML in iPhone. I’m able to call the service URL but when 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>




   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. I don’t know what’s wrong. What should I change? How can I get the value of the ID attribute?

Any help would be appreciated. Thanks in advance.

Answer 1

id is not attribute of the name. Put code in didEndElement:
define strVal NSString in .h;

Inside found character:
{
   strVal=string;
}

Inside parserDidEndElement method:
     {

       if ([elementName isEqualToString:@"Id"]) {
        NSString *name=strVal;

    }
    }

This will work for you.
