How to deserialize SOAP?

Question

go

I'm trying to deploy SOAP to a GO structure, it doesn't return an error, but the status field remains empty. What am I doing wrong?

package main

import (
  "fmt"
  "encoding/xml"
)

type myEnvelope struct {
  XMLName xml.Name `xml:"Envelope"`
  Body    methodResponseData
}

type methodResponseData struct {
  XMLName xml.Name
  Status  string `xml:"responseData>status"`
}

func main() {
  resp := methodResponseData{}
  resp.XMLName.Local = "SOAP-ENV:methodResponse"

  envelope := myEnvelope{
    Body: resp,
  }
  envelope.XMLName.Local = "Envelope"
  envelope.Body.XMLName.Local = "Body"

  raw := []byte(`
      <?xml version="1.0" encoding="UTF-8"?>
      <SOAP-ENV:Envelope> 
    				<SOAP-ENV:Body> 
        				<SOAP-ENV:methodResponse> 
            					<responseData> 
                					<status>OK</status> 
            					</responseData> 
        				</SOAP-ENV:methodResponse> 
    				</SOAP-ENV:Body> 
      </SOAP-ENV:Envelope>
  `)
  err := xml.Unmarshal(raw, &envelope)
  if err != nil {
    fmt.Printf("something wrong %s", err)
  }
  fmt.Printf("%s", envelope.Body.Status)
}

I don't know much about Go, so this might look weird.

package main

import (
  "fmt"
  "encoding/xml"
)

type Body struct {
  XMLName xml.Name
  Status  string `xml:"methodResponse>responseData>status"`
}

type Envelope struct {
  XMLName xml.Name
  Body    Body `xml:"Body"`
}

func main() {

  var envelope Envelope

  raw := []byte(`
      <?xml version="1.0" encoding="UTF-8"?>
      <SOAP-ENV:Envelope> 
    				<SOAP-ENV:Body> 
        				<SOAP-ENV:methodResponse> 
            					<responseData> 
                					<status>OK</status> 
            					</responseData> 
        				</SOAP-ENV:methodResponse> 
    				</SOAP-ENV:Body> 
      </SOAP-ENV:Envelope>
  `)
  err := xml.Unmarshal(raw, &envelope)
  if err != nil {
    fmt.Printf("something wrong %s", err)
  }
  fmt.Printf("Status: %s", envelope.Body.Status)
}

OUT

Status: OK
Process finished with exit code 0

Don't reinvent the wheel and find a library to work with soap. Protocols are invented for this, in order to standardize some things and then use libraries.
