Golang Marshal dynamic xml element name
The xml file consists of two elements. These elements have the same structure, except for the same element name. I tried to set the value of the XMLName property, but it didn't work.
Xml:
<!-- first element -->
<PERSON>
<ELEM1>...</ELEM1>
<ELEM2>...</ELEM2>
<ELEM3>...</ELEM3>
<ELEM4>...</ELEM4>
</PERSON>
<!-- second element -->
<SENDER>
<ELEM1>...</ELEM1>
<ELEM2>...</ELEM2>
<ELEM3>...</ELEM3>
<ELEM4>...</ELEM4>
</SENDER>
Is it possible to define such a structure so that the element name is dynamic?
type Person struct {
XMLName string `xml:"???"` // How make this dynamic?
e1 string `xml:"ELEM1"`
e2 string `xml:"ELEM2"`
e3 string `xml:"ELEM3"`
e4 string `xml:"ELEM4"`
}

The documentation says that the field XMLName
must be of type xml.Name
.
type Person struct {
XMLName xml.Name
E1 string `xml:"ELEM1"`
// ...
}
Set the element name using the field Local
xml.Name
:
person := Person {
XMLName: xml.Name { Local: "Person" },
// ...
}
(Also, E1-E4 must be exported to be included in the XML output).
