Retrieving the Response from Backend

Upon performing request using [request startAsynchronous], the response will arrive at either - (void)requestFailed:(SDMHttpRequest*) request {} or  - (void)requestFinished:(SDMHttpRequest*) request {} depending on whether the transaction was a Failure or Success respectively.

Add the following in the - (void)requestFinished(SDMHttpRequest*) request method:

   /* The response parsing depends on the type of document queried whether its service document or metadata or
    OData*/
    if([[self.m_reqTypeDic objectForKey:KEY_REQUEST_TYPE] isEqualToString:SERVICE_DOC_REQUEST]) 
    {   
      /*Initialize the SDMODataServiceDocumentParser class object for parsing response service document
        data*/         
        SDMODataServiceDocumentParser
        *svcDocParser=[[[SDMODataServiceDocumentParser alloc]init]autorelease];              
        /* Parses the service document XML and converts it to an Objective-C service document object.*/
           [svcDocParser parse:[request responseData]];
          /* Service document instance can be accessed via the "serviceDocument" property of the parser after
             parsing*/            
             SDMODataServiceDocument
             *svcDoc=svcDocParser.serviceDocument;
         }

         else if([[self.m_reqTypeDic objectForKey:KEY_REQUEST_TYPE] isEqualToString:METADATA_REQUEST])
         { 
         /*Initialize the SDMODataMetaDocumentParser class object for parsing response meta data*/ 
           SDMODataMetaDocumentParser *metaDocParser=[[[SDMODataMetaDocumentParser
           alloc]initWithServiceDocument:svcDoc]autorelease]; 

           /*Parses and matches the schema with the service document and its collections.*/     

             [metaDocParser parse:[request responseData]];   

             /* The parser creates the schema of the input service document's collections and returns a collection by name */
               SDMODataCollection *carrierCollection=[svcDoc.schema getCollectionByName:@"CarrierCollection"];

               }  
               else if([[self.m_reqTypeDic objectForKey:KEY_REQUEST_TYPE] isEqualToString:ODATA_REQUEST])
               {
               /* Initialize the SDMODataDataParser class object for parsing any "inlined"entries or feed(s) when service

                  SDMODataDataParser *dataParser=[[[SDMODataDataParser alloc]initWithEntitySchema: carrierCollection.entitySchema andServiceDocument: svcDoc]autorelease];
                              
               /*Parses a feed or an entry xml.*/    
                 [dataParser parse:[request responseData]];                              

               /* The array of parsed entry/entries can be accessed via the "entries" property of the parser after parsing.
                  Array of SDMOdata Entries can be iterated and diplay the requisite data in tableview */

                  NSMutableArray * carriersList=[l_dataParser.entries retain];
         }
