Good afternoon!

I need to get information that is contained in divs in an HTML.

HTML:

<div id="fundo_conteudo_noticia_setor" class="textogeral marrom">
            <div id="data_noticia_setor" class="textogeral_bold verde">Data</div>
            <div id="conteudo_noticia_setor">
                <a href="noticia_interna.asp?id=13692" class="sublinhado verde">
                    <span class="titulo_destaque_bold verde">Título<br>
                        <span class="titulo_destaque verde">Categoria</span>
                    </span>
                    <br><br>
                </a>
                Resumo do conteúdo...
            </div>
            </div>
            <div id="seta_noticia_setor"><i class="fa fa-angle-right fa-3x verde"></i></div>
        </div>

And this is the PHP I'm using to get the info. However, by picking node $ result ['title'], it is returning child elements together.

if(!$data = file_get_contents("meusiteteste.com.br")){
    $results = false;
}
else {

    $html = iconv('UTF-8', 'ISO-8859-1//TRANSLIT', $data);
    $doc = new DomDocument();
    @$doc->loadHTML($html);
    $xpath = new DomXpath($doc);
    $entries = $xpath->query("//div[@id=\"conteudo_noticia_setor\"]");
    $results = array();

    foreach ($entries as $entry){

        $node = $xpath->query("a/attribute::href", $entry);
        $result['link'] = $node->item(0)->value;

        echo $result['link'].'<br>';

        $node = $xpath->query("a/span[contains(@class, 'titulo_destaque_bold')]", $entry);
        $result['titulo'] = $node->item(0)->nodeValue;

        echo $result['titulo'].'<br><br>';

    }
}

You are printing: TitleCategory I would like to take the contents of the span that is contained inside, but I do not know how to proceed.
