<?php

$dom = Dom\HTMLDocument::createFromString(
    '<!DOCTYPE html><body><ul id="list"><li>Two</li></ul></body>',
    LIBXML_NOERROR
);

$list = $dom->getElementById('list');

$list->firstElementChild->insertAdjacentHTML(
    Dom\AdjacentPosition::BeforeBegin,
    '<li>One</li>'
);
$list->insertAdjacentHTML(
    Dom\AdjacentPosition::BeforeEnd,
