Golang XML解析问题

Question

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!

<?xml version="1.0" encoding="utf-8"?>

Answer 1

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.

net/http example available
