Something like this: https://play.golang.com/p/TqlsfIV2BSF

package main

import (
  "encoding/xml"
  "fmt"
)

type MyData struct {
  XMLName    xml.Name
  Attributes []xml.Attr `xml:",attr"`
}

func main() {
  v := MyData{
    XMLName: xml.Name{Local: "somename"},
    Attributes: []xml.Attr{
      {Name: xml.Name{Local: "attr1"}, Value: "val1"},
      {Name: xml.Name{Local: "attr2"}, Value: "val2"},
    },
  }

  rawData, _ := xml.Marshal(v)
  fmt.Println(string(rawData))
}
