iOS开发后台请求报错，帮忙看下XML格式哪里有问题急急急！！！大神们

报错：Entity: line 1: parser error : Start tag expected, '以下为请求XML，用的是ASIHTTPRequest请求框架，不知错在何处
com.portal.android.ExecuteAndroidchangeState

请求数据代码：
NSString *kvr = [NSString stringWithFormat:@"",@"",cell.shipNameTextField.text,cargoRemark,self.dockModel.t2,self.berthModel.t2,cargoType,self.cargoModel.t2,self.cargoModel.t1,cell.cargoWeightTextField.text,cell.billInfoTextField.text,@"",cell.delegateTextField.text,@"NODECL",appDelegate.userInfo.ORG_NAME,appDelegate.userInfo.ORG_ID,appDelegate.userInfo.USER_ID,appDelegate.userInfo.USER_NAME,appDelegate.userInfo.USER_ID,appDelegate.userInfo.USER_NAME,self.personModel.t2];
[req sendRequest:@"com.portal.android.ExecuteAndroid" metherName:@"changeState" kvrStr:kvr andTag:4001 andUrl:WebServeUrl];

(void)sendRequest:(NSString )classPath metherName:(NSString )metherName kvrStr:(NSString )kvrStr andTag:(NSInteger) tag andUrl:(NSString )url
{
__block ASIHTTPRequest *request = [[ASIHTTPRequest alloc] initWithURL:[NSURL URLWithString:url]];
// NSLog(@"%@",WebServeUrl);
NSMutableString *requestXml = [[NSMutableString alloc] init];
[requestXml appendString:@""];
[requestXml appendString:@""];
[requestXml appendString:@""];
NSString *name = [NSString stringWithFormat:@"%@%@",classPath,metherName];
[requestXml appendString:name];

[requestXml appendString:kvrStr];
[requestXml appendString:@""];
[requestXml appendString:@""];

//NSLog(@"%@",requestXml);
NSData *requestData = [requestXml dataUsingEncoding:NSUTF8StringEncoding];

[request appendPostData:requestData];
[request setRequestMethod:@"post"];

//请求执行完的回掉
[request setCompletionBlock:^{

<code>   //NSLog(@"Success");
   NSData *decompressData = [request responseData];
   GDataXMLDocument *doc = [[GDataXMLDocument alloc] initWithData:decompressData options:0 error:Nil];
   GDataXMLElement *rootElement = [doc rootElement];
   NSArray *result = [rootElement elementsForName:@"result"];
   for (GDataXMLElement *response in result) {
       NSString *code = [[response attributeForName:@"code"] stringValue];
       NSString *msg = [[response attributeForName:@"msg"] stringValue];
       //01是成功，其余是错误
       if (![code isEqualToString:@"01"]) {
           [self showAlert:msg];
       } else {
           NSArray *datasetArray = [rootElement elementsForName:@"kvdata"];
           NSArray *kvadaArray = [rootElement elementsForName:@"dataset"];
           GDataXMLElement *data = [kvadaArray objectAtIndex:0];
           NSArray *dataArray = [data elementsForName:@"data"];
           if ([datasetArray count] > 0) {
               [_delegate didReceiveData:datasetArray andTag:tag];
           }else{
               [_delegate didReceiveData:dataArray andTag:tag];
           }
       }
   }
   request = nil;</code>

}];

//异常出现
[request setFailedBlock:^{

<code>   //NSLog(@"Failed");
   [self showAlert:@"网络请求失败，请稍后再试"];
   //        [_delegate didFairToReceiveData:nil andTag:tag];</code>

}];

[request startAsynchronous];

}];

[request startAsynchronous];
}

由于把请求数据加密了，请求回调时处理数据未解密，所以导致了错误

格式没错哦，你用一个支持xml的ide打开一下就可以知道有没有语法错误。。。

请求数据是不是有错误？
能不能把你打印请求数据的代码贴出来
