Error unmarshalling responses from VirtualBox vboxwebsrv about gowsdl

Can you confirm if the issue is similar to the one described here? #17. My comment on it here: #17 (comment)

@c4milo I think this is a different problem. In that case, the NRCS web service is rejecting the request created by gowsdl and returning a SOAP fault due to how the namespaces in the request are specified.

In my case, the problem is with unmarshalling the response returned by the web service. Specifically, the fact that the xmlns:vbox="http://www.virtualbox.org/" is declared on the Envelope means that when gowsdl goes to parse the innerxml of the Body tag, it doesn't have the namespace mapping available. This makes it think that vbox is an undeclared prefix when it parses respEnvelope.Body.Content here:

gowsdl/generator/soap.go

Line 133 in 8413716

body := respEnvelope.Body.Content

Looks like there's a proposal to expose the namespace bindings in the decoder: golang/go#12406

This could help with this issue, though it doesn't help with Go 1.5.

I managed to write some code that I think does the right thing for dynamic unmarshalling: https://github.com/md5/gowsdl-vboxwebsrv-test/blob/0f89b3888adf2c3ccb06b69dceec39c669783e97/unmarshal.go

It's getting late for me here, but I may have some time in the next few days to try to work it into a PR for gowsdl. In the meantime, have a look.

Please bear in mind that I'm still learning Go, so I may have done some silly things here...

hey @md5, thanks for looking into this. I think you are definitely on the right track. We need to parse the whole response in one shoot so namespaces declared at the root of the document are considered.
