Generate XML

<?php

$xmlBuilder = XmlBuilder::create();

$xmlBuilder
  ->element('root')
    ->element('ns:element', 'value', 'http://ns/ns')
      ->attr('ns:attr1', 'value1', 'http://ns/ns')
      ->attr('attr2', 'value2')
    ->end()
  ->end()
;

echo $xmlBuilder->getXml(true);

Result:

<?xml version="1.0" encoding="utf-8"?>
<root>
  <ns:element xmlns:ns="http://ns/ns" ns:attr1="value1" attr2="value2">value</ns:element>
</root>

<?php

$xmlBuilder = XmlBuilder::create();

$xmlBuilder
  ->element('root')
    ->element('user')
      ->element('addresses')->reference($addresses)->end()
    ->end()
  ->end()
;

$addresses->element('address', 'value1')->end();
$addresses->element('address', 'value2')->end();

echo $xmlBuilder->getXml(true);
