使用Cocoa向服务器发送和接收XML [英] Sending and receiving XML, to and from server using Cocoa

问题描述

我有一些XML数据，我想传送到网络服务器，响应也是在XML。

I have some XML data that I want to transmit to a web server and the response is also in XML.

我试图使用Cocoa解析XML 。我已遵循此文档创建XML和发送它，但是该文档不能很好地解释如何从服务器接收XML响应。

I am trying to use Cocoa to parse the XML. I have followed this document to create the XML and transmit it, but the document doesn't explain very well how you can receive the XML response from the server.

我没有找到任何好的例子使用google。有人可以指点我一些好的资源来集成XML和Cocoa吗？感谢

I haven't been able to find any good examples using google either. Can someone point me to some good resources to integrate XML and Cocoa? Thanks

推荐答案

您发布的文章看起来相当全面。你实现了三个连接委托方法？执行 transmitXMLRequest：后， NSURLConnection 对象将自动开始加载数据。您的代理将看到以下内容：

The article that you posted looks pretty comprehensive. Did you implement the three connection delegate methods? Once you execute transmitXMLRequest:, the NSURLConnection object will automatically start loading in data. Your delegate will see the following:

connection:didReceiveResponse:
connection:didReceiveData:
connection:didReceiveData:
connection:didReceiveData:
...
connectionDidFinishLoading:

您在每个代理方法中放置的代码至关重要。没有它，不会从服务器中检索任何数据。

The code that you place in each of those delegate methods is critical. Without it, no data is ever retreived from the server.

在第3页的文章中，将介绍如何创建 NSXMLDocument 从接收的数据。 NSXMLDocument简化了解析XML文件的过程。有关详情，请参阅Apple的基于树的XML编程指南。

In your article, on page 3, it describes how to create an NSXMLDocument from the received data. NSXMLDocument simplifies the process of parsing an XML file. For details, see Apple's Tree-Based XML Programming Guide.
