我是电话编程的新手。使用下面的代码我得到响应表单 web 服务
NSString *soapMessage=[NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
"<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
"<soap:Body>\n"
"<OnlineStatus xmlns=\"http://tempuri.org/\">\n"
"<CafeName>Cyber Cafe Name</CafeName>\n"
"<FromDate>2012-03-01</FromDate>\n"
"<ToDate>2013-05-03</ToDate></OnlineStatus>\n"
"</soap:Body>\n"
"</soap:Envelope>"];
NSLog(@"%@",soapMessage);
NSURL *url = [NSURL URLWithString:@"http://www.ebidmanagerdemo.com/gjHouseOnline/xml/XMLDataService.asmx"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: @"http://tempuri.org/OnlineStatus" forHTTPHeaderField:@"Soapaction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if(theConnection) {
webData = [NSMutableData data];
}
else {
NSLog(@"theConnection is NULL");
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
NSLog(@"%@",msgLength);
}
}
我收到以下格式的回复

我没有得到标签末尾的 < 和 >。我在这个响应中没有得到开始标签和结束标签。在 xml 中也没有
并使用下面的代码我正在尝试解析数据，但这里它没有加载数据NSXMLParser
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(@"DONE. Received Bytes: %d", [webData length]);
NSString *theXML = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding];
NSLog(@" getting in xml %@",theXML);
xmlParser = [[NSXMLParser alloc]initWithData:webData];
[xmlParser setDelegate: self];
[xmlParser setShouldResolveExternalEntities: YES];
[xmlParser parse];
NSLog(@" iiiiii %@",xmlParser);
}
它的显示NSXMLParser如下所示。我想使用开始和结束元素解析数据。
