解析IOS中的XML響應

Question

我正在創建一個IOS應用程序。我必須使用SOAP Web服務來獲取一些細節。所以我用SUDZ-C來生成存根。我可以調用Web服務並獲得響應。但我無法解析迴應。以下是XML響應。

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
    <soapenv:Body> 
     <ViewAppTrackResponse xmlns="http://service.cmp.app.com"> 
     <ViewAppTrackResponseReturn> 
      <ns1:monthBO xmlns:ns1="http://response.cmp.app.com"> 
       <monthListItem> 
        <ns2:date xmlns:ns2="http://bean.cmp.app.com">1-2-2014, Saturday (nonworking day)</ns2:date> 
        <ns3:lockStatus xmlns:ns3="http://bean.cmp.app.com">N</ns3:lockStatus> 
        <ns4:dailyTime xsi:nil="true" xmlns:ns4="http://bean.cmp.app.com"/> 
        <ns5:taskListNew xsi:nil="true" xmlns:ns5="http://bean.cmp.app.com"/> 
       </monthListItem> 
       <monthListItem> 
        <ns6:date xmlns:ns6="http://bean.cmp.app.com">2-2-2014, Sunday (nonworking day)</ns6:date> 
        <ns7:lockStatus xmlns:ns7="http://bean.cmp.app.com">N</ns7:lockStatus> 
        <ns8:dailyTime xmlns:ns8="http://bean.cmp.app.com">04:00</ns8:dailyTime> 
        <ns9:taskListNew xmlns:ns9="http://bean.cmp.app.com"> 
        <taskListItem> 
         <ns9:trackId>1070</ns9:trackId> 
         <ns9:taskId>14</ns9:taskId> 
        </taskListItem> 
        <taskListItem> 
         <ns9:trackId>1094</ns9:trackId> 
         <ns9:taskId>44</ns9:taskId> 
        </taskListItem> 
        </ns9:taskListNew> 
       </monthListItem> 
       <monthListItem> 
        <ns10:date xmlns:ns10="http://bean.cmp.app.com">3-2-2014, Monday</ns10:date> 
        <ns11:lockStatus xmlns:ns11="http://bean.cmp.app.com">N</ns11:lockStatus> 
        <ns12:dailyTime xmlns:ns12="http://bean.cmp.app.com">08:00</ns12:dailyTime> 
        <ns13:taskListNew xmlns:ns13="http://bean.cmp.app.com"> 
        <taskListItem> 
         <ns13:trackId>1071</ns13:trackId> 
         <ns13:taskId>14</ns13:taskId> 
        </taskListItem> 
        <taskListItem> 
         <ns13:trackId>1073</ns13:trackId> 
         <ns13:taskId>44</ns13:taskId> 
         </taskListItem> 
        </ns13:taskListNew> 
       </monthListItem> 
      </ns1:monthBO> 
      <ns14:userId xsi:nil="true" xmlns:ns114="http://response.cmp.app.com"/>5</ns14:userId> 
     </ViewAppTrackResponseReturn> 
     </ViewAppTrackResponse> 
    </soapenv:Body> 
</soapenv:Envelope> 

任何人都可以幫我解析這個迴應。這對我有幫助。

LibXML2包含在Cocoa中。

Answer 2

可以使用的NSXMLParser類解析this.Using其委託的方法可以解析。我張貼我的嘗試解析你的xml.It不完成。我給你一個基本的解析代碼。你必須做剩下的。 這裏的「xmlInput」是與你的xmlstring類型的NSString類型。

NSData* xmlData = [xmlInput dataUsingEncoding:NSUTF8StringEncoding]; 

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

創建一個xmlparser對象並輸入您的xmlData.Set其委託。

 //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; 
     }
