XML Response

Learn how to send XML responses in Iris.

Basic XML Response

package main

import "github.com/kataras/iris/v12"

type Person struct {
    XMLName   xml.Name `xml:"person"`
    ID        int      `xml:"id,attr"`
    FirstName string   `xml:"firstname"`
    LastName  string   `xml:"lastname"`
    Age       int      `xml:"age"`
}

func main() {
    app := iris.New()

    app.Get("/xml", func(ctx iris.Context) {
        person := Person{
            ID:        1,
            FirstName: "John",
            LastName:  "Doe",
            Age:       25,
        }

        ctx.XML(person)
    })

    app.Listen(":8080")
}

Custom XML Header

app.Get("/custom", func(ctx iris.Context) {
    ctx.ContentType("application/xml")
    ctx.Header("X-Custom", "value")

    data := struct {
        Message string `xml:"message"`
    }{
        Message: "Hello World",
    }

    ctx.XML(data)
})

XML Collection

type Users struct {
    XMLName xml.Name `xml:"users"`
    Users   []User   `xml:"user"`
}

type User struct {
    ID   int    `xml:"id,attr"`
    Name string `xml:"name"`
}

app.Get("/users", func(ctx iris.Context) {
    users := Users{
        Users: []User{
            {ID: 1, Name: "John"},
            {ID: 2, Name: "Jane"},
        },
    }

    ctx.XML(users)
})

Best Practices

1. Structure:

   • Use proper tags
   • Follow conventions
   • Document schema
   • Handle namespaces
   • Validate output

2. Performance:

   • Enable compression
   • Cache responses
   • Optimize size
   • Monitor encoding
   • Handle timeouts

3. Security:

   • Validate input
   • Escape output
   • Set headers
   • Handle errors
   • Monitor usage

4. Maintenance:

   • Document schema
   • Update structure
   • Monitor changes
   • Regular testing
   • Review security
