Installation

With npm do:

$ npm install xml-writer2

Examples

Basic

const XMLWriter = require("xml-writer2");
const xw = new XMLWriter();
xw.startDocument();
xw.startElement("root");
xw.writeAttribute("foo", "value");
xw.text("Some content");
xw.endDocument();

console.log(xw.toString());

Output:

<?xml version="1.0"?>
<root foo="value">Some content</root>

Tip: If you want your XML indented use new XMLWriter(true) or new XMLWriter('\t'), for instance, if you want to use a custom string for indentation.

Chaining

var XMLWriter = require("xml-writer2");
xw = new XMLWriter();
xw.startDocument()
  .startElement("root")
  .writeAttribute("foo", "value")
  .writeElement("tag", "Some content");

console.log(xw.toString());

Output:

<?xml version="1.0"?>
<root foo="value"><tag>Some content</tag></root>

Tolerant

var XMLWriter = require("xml-writer2");
xw = new XMLWriter();
xw.startElement("root").writeAttribute("foo", "value").text("Some content");

console.log(xw.toString());

Output:

<root foo="value">Some content</root>

Extensible

var XMLWriter = require("xml-writer2"),
  fs = require("fs");
var ws = fs.createWriteStream("/tmp/foo.xml");
ws.on("close", function () {
  console.log(fs.readFileSync("/tmp/foo.xml", "UTF-8"));
});
xw = new XMLWriter(false, function (string, encoding) {
  ws.write(string, encoding);
});
xw.startDocument("1.0", "UTF-8")
  .startElement(function () {
    return "root";
  })
  .text(function () {
    return "Some content";
  });
ws.end();

Output:

<?xml version="1.0" encoding="UTF-8"?>
<root>Some content</root>
