$url = new Url($loc);
$url->setLastMod($lastMod);
$url->setChangeFreq($changeFreq);
$url->setPriority($priority);
$urlset = new Urlset();
$urlSet->add($url);
$driver = new XmlWriterDriver();
$urlset->accept($driver);
echo $driver->getOutput();
Generating a parent (<sitemapindex>) sitemap.
<?php
use Aterbonus\Sitemap\SitemapIndex;
use Aterbonus\Sitemap\Sitemap;
use Aterbonus\Sitemap\Drivers\XmlWriterDriver;
// Sitemap entry.
$url = new Sitemap($loc);
$url->setLastMod($lastMod);

$urlset = new SitemapIndex();
$urlSet->add($url);
$driver = new XmlWriterDriver();
$urlset->accept($driver);
echo $driver->output();
The following extensions are supported: Image, Link, Mobile, News and Video. They work in the following way (taking image as an example):
<?php
use Aterbonus\Sitemap\Urlset;
use Aterbonus\Sitemap\Url;
use Aterbonus\Sitemap\Extensions\Image;
$url = new Url($loc);
$url->setLastMod($lastMod);
$url->setChangeFreq($changeFreq);

$url->addExtension($image);

Processing Instructions
You can add processing instructions on the output as such.
<?php
use Aterbonus\Sitemap\Drivers\XmlWriterDriver;
$driver = new XmlWriterDriver();
$driver->addProcessingInstructions('xml-stylesheet', 'type="text/xsl" href="/path/to/xslt/main-sitemap.xsl"');
Which will add before the document starts.
<?xml-stylesheet type="text/xsl" href="/path/to/xslt/main-sitemap.xsl"?>
Comments

<?php
use Aterbonus\Sitemap\Drivers\XmlWriterDriver;
$date = date('Y-m-d H:i:s');
$driver = new XmlWriterDriver();
$driver->addComment('This XML file was written on ' . $date . '. Bye!');
Which will render out.
<?xml version="1.0" encoding="UTF-8"?>
<!--This XML file was written on 2018-06-24 15:57:23. Bye!-->
