How to create a CDATA node of xml with go?

Question

I have the following struct:

type XMLProduct struct {
    XMLName          xml.Name `xml:\"row\"`
    ProductId        string   `xml:\"product_id\"`
    ProductN

Expanding on the answer by @BeMasher, you can use the xml.Marshaller interface to do the work for you.

package main

import (
    "encoding/xml"
    "os"
)

type SomeXML struct {
    Unescaped CharData
    Escaped   string
}

type CharData string

func (n CharData) MarshalXML(e *xml.Encoder, start xml.StartElement) error {
    return e.EncodeElement(struct{
        S string `xml:",innerxml"`
    }{
        S: "",
    }, start)
}

func main() {
    var s SomeXML
    s.Unescaped = "http://www.example.com/?param1=foo¶m2=bar"
    s.Escaped = "http://www.example.com/?param1=foo¶m2=bar"
    data, _ := xml.MarshalIndent(s, "", "\t")
    os.Stdout.Write(data)
}

Output:

    
    http://www.example.com/?param1=foo&param2=bar
