It seems to me like your unmarshaling isn't actually working (look inside the decoded data).
Here's an alternative version: https://play.golang.org/p/CAChEa4-Kp It's still not exactly right, as the DID tag is in the empty namespace in the original XML, but is in os.xsd.v1 in the encoded version. Does that cause your decoders to fail? That's a bug in the encoding/xml package, as I don't think it's possible to explicitly specify the empty namespace in a struct tag. In your code, I believe that struct tags like `xml:"os:QUERYResponse"` are only working by accident, because encoding/xml isn't interpreting it as a namespace-prefixed tag name but instead just treating it as a whole tag, so just printing it as is. That's probably why unmarshaling isn't working. BTW, I'd suggest trying a fork of encoding/xml that gets namespaces somewhat more right: github.com/juju/xml. It was in the standard library at some point, and hopefully will get there again when I have some energy to do it. cheers, rog.
