Escape sequences are not preserved

[jzelinskie]

Hey, thanks again for pushing out the previous fixes so quickly. After fixing that, the troublesome document revealed another inconsistency: converting XML to JSON handles escape sequences, but encoding JSON to XML does not.

package main

import (
	"fmt"

	"github.com/clbanning/mxj/v2"
)

func main() {
	xmap, _ := mxj.NewMapXml([]byte("<p>me &amp; you</p>"), true)
	jsonBytes, _ := xmap.Json()
	jmap, _ := mxj.NewMapJson(jsonBytes)
	newXmlBytes, _ := jmap.Xml()

	fmt.Println(string(newXmlBytes))
	// prints:   <p>me & you</p>
	// expected: <p>me &amp; you</p>
}

Unfortunately, this is a feature of the encoding/xml decoder - https://golang.org/pkg/encoding/xml/#CharData.

You can see it in action here: https://play.golang.org/p/-UR1SmwwiwN.

However, if you toggle mxj.XMLEscapeCharsDecoder() that should address your issue. Try -

package main

import (
	"fmt"

	"github.com/clbanning/mxj/v2"
)

func main() {
        mxj.XMLEscapeCharsDecoder()
	xmap, _ := mxj.NewMapXml([]byte("<p>me &amp; you</p>"), true)
	jsonBytes, _ := xmap.Json()
	jmap, _ := mxj.NewMapJson(jsonBytes)
	newXmlBytes, _ := jmap.Xml()

	fmt.Println(string(newXmlBytes))
	//prints: <p>me &amp; you</p>
}
