<div>{{ ApiRef("DOM") }}</div>



<p>Para cada página carregada no browser, existe um objeto <code><strong>Document</strong></code>. A interface <code>Document</code> serve como um ponto de entrada para o conteúdo da Página ( a árvore DOM, incluindo elementos como {{HTMLElement("body")}} e {{HTMLElement("table")}}) e provê funcionalidades globais ao documento (como obter a URL da página e criar novos elementos no documento).</p>

<p>{{inheritanceDiagram}}</p>

<p>Um objeto document pode ser obtido por meio de várias APIs:</p>

<ul>
 <li>A mais comum; você trabalha com o script do documento que está rodando o script com o objeto document. (O mesmo document também pode ser referenciado como {{domxref("window.document")}}.)</li>
 <li>O documento de um iframe através da propriedade <code><a href="/en-US/docs/Web/API/HTMLIFrameElement#Properties" title="DOM/HTMLIFrameElement#Properties">contentDocument</a>.</code></li>
 <li>O <a href="/en-US/docs/Web/API/XMLHttpRequest#responseXML" title="XMLHttpRequest#responseXML"><code>responseXML</code> de um objeto <code>XMLHttpRequest</code></a>.</li>
 <li>O documento ao qual um determinado node ou elemento pertence pode ser recuperado usando a propriedade do node {{domxref("Node.ownerDocument","ownerDocument")}}</li>
</ul>

<p>Dependendo do tipo do documento (e.g. <a href="/en-US/docs/HTML" title="HTML">HTML</a> ou <a href="/en-US/docs/XML" title="XML">XML</a>), diferentes APIs estarão disponívels no objeto <code><strong>Document</strong></code>.</p>

<p>Todo objeto <strong><code>Document</code></strong> implementa a interface <code><a href="http://dom.spec.whatwg.org/#interface-document">Document</a></code> (e consequentemente as interfaces {{domxref("Node")}} e {{domxref("EventTarget")}}). Portanto, as principais propriedades e métodos documentados nesta página estarão disponíveis para todos os tipos de documents.</p>

<ul>
 <li>Em navegadores mais atuais, alguns documentos (ex: aqueles que são servidos com o Content-Type <code>text/html</code>) também implementam a interface {{domxref("HTMLDocument")}}.</li>
 <li>Em navegadores mais atuais, documentos SVG implementam a interface {{domxref("SVGDocument")}}.</li>
</ul>

<p>No futuro, todas essas interfaces irão ser divididas na interface <code>Document</code>.</p>
