I'm trying to communicate with a SOAP service from my go program but I'm having difficulties to use the xml package.
Most of the requests I have to send have the following format:
<s:Envelope xmlns="namespace1">
<s:Body>
<FunctionName xmlns=“namespace2”/>
</s:Body>
</s:Envelope>
I feel I have to create one type for each request I want to make, as FunctionName
changes... Here's the code I use so far.
It would be nice if I could have a single type with the FunctionName
as an attribute but I just can't figure out how... To make it clearer, I would like to put a variable instead of FunctionName
inside xml:"s:Body>FunctionName"
.
Thanks a lot for your help!

You can use an xml.Name
field to specify the tag name you want it in the XML output. Note that with xml.Name
you can also specify the namespace, so you don't even need Command.Field
anymore which you only used to set the namespace attribute.
So here is your modified code:
type Command struct {
XMLName xml.Name
}
type XMLEnvelop struct {
XMLName xml.Name `xml:"s:Envelope"`
Xmlns string `xml:"xmlns:s,attr"`
FunctionName Command `xml:"s:Body>FunctionName"`
}
v := &XMLEnvelop{Xmlns: "namespace1",
FunctionName: Command{xml.Name{"namespace2", "MyFuncName"}}}
output, err := xml.MarshalIndent(v, "", " ")
if err != nil {
fmt.Printf("error: %v\n", err)
}
// Write the output to check
os.Stdout.Write(output)
Output (try it on the Go Playground):
<s:Envelope xmlns:s="namespace1">
<s:Body>
<MyFuncName xmlns="namespace2"></MyFuncName>
</s:Body>
</s:Envelope>
