How Can I Marshal Dynamic XML Element Names in Go?

Marshaling Dynamic XML Element Names in Golang

Problem

An XML file contains multiple elements with similar structures, but different names (e.g., PERSON and SENDER). The goal is to define a struct that allows for a dynamic element name.

Solution

While initially attempting to set the element name using the XMLName property wasn't successful, it is possible to achieve this by leveraging the following strategies:

• Use the xml.Name type for XMLName: According to the documentation, the XMLName field requires the xml.Name type.

type Person struct {
    XMLName xml.Name
    E1 string `xml:"ELEM1"`
    // ...
}

• Set the element name dynamically through xml.Name.Local: To assign a dynamic element name, use the Local field of xml.Name.

person := Person { 
    XMLName: xml.Name { Local: "Person" },
    // ...
}

• Exported fields for XML inclusion: Ensure that the fields representing elements (e.g., E1 in this example) are exported by starting with an uppercase letter. This allows them to be included in the XML output.

Example
