Golang XML Parsing issue
问题
我刚刚开始尝试使用谷歌的Go（Golang）语言，并遇到了一个我想高效解决的问题。我想从一个在线可用的XML文件中提取一些数据（我将其作为轮询会话的响应获取），但我不知道如何入手。我应该下载页面的源代码，将其存储在本地并从中提取数据，还是有可能在不下载整个页面的情况下提取数据？谢谢！

I have just started experimenting with Google's GO (Golang) language, and have run into a problem that I would like to solve efficiently.
So I would like to extract some data from an XML file, that is available online (I get it as the response of a polling session), but I don't know how to get started. Should I download the source code of the page, store it locally and extract the data that way or is there a possibility to extract the data without downloading the whole thing? Thank you!

由于它可以在线使用，您可以使用net/http客户端来获取XML。然后，您可以使用encoding/xml包将响应体转换为结构体对象，它具有xml.Unmarshal方法将XML字符串转换为结构体 - 因此您应该先编写结构体。
net/http示例可在以下链接找到：

英文:
Since its available online you can use net/http client to retrieve the xml. Then you can use encoding/xml package and convert the response body to struct object, it has xml.Unmarshal method to convert xml string to struct - hence you should write the struct first.
