Escaping ampersand character with following semicolon

[Quty]

Following code

const xmlbuilder = require('xmlbuilder2');

const xml = xmlbuilder.create({ encoding: 'UTF-8' })
    .ele('root').txt('5&ABC;')
    .end({ prettyPrint: true });

console.log(xml);

outputs

<?xml version="1.0" encoding="UTF-8"?>
<root>5&ABC;</root>

Is it expected that #txt method doesn't escapes & character in 5&ABC;?

I think the problem is the way that xmlbuilder2 tries to avoid double-encoding XML escape sequences. Your string is being treated as an XML entity by nonEntityAmpersandRegex so the ampersand doesn't get replaced.

I'm currently hitting a problem with the same code, but that's because I wan't the ampersand in the text b&w to be encoded and xmlbuilder2 seems to have been deliberately built to not do that.

This appears to be double-encoding protection.

In my opinion, the method should either accept raw data and encode all invalid characters, or accept prepared data and not perform any conversions.

Now I am forced to use third party tools to encode the text before passing it to #txt method.
