Solution:

You need to fetch the parent nodes (texto), iterate and save each child node as XML:

$documento = new SimpleXMLElement(getXMLstring());

foreach ($documento->xpath('//texto') as $texto) {
  $result = '';
  foreach ($texto->children() as $content) {
    $result .= $content->asXML(); 
  }

  var_dump($result);
}

Output:

string(59) "<dl>
<dt>1. Poder adjudicador: </dt>
<dd>
[...]
</dd>
</dl>"

SimpleXML is an abstraction focused on element nodes. It has limits. If thetexto element can have non-element child nodes they will not be included. In this case you need to use DOM.

$document = new DOMDocument();
$document->loadXML(getXMLString());
$xpath = new DOMXpath($document);

foreach ($xpath->evaluate('//texto') as $texto) {
  $result = '';
  foreach ($texto->childNodes as $content) {
    $result .= $document->saveXML($content); 
  }

  var_dump($result);
}

AdditionallyDOMXpath::evaluate() supports full Xpath 1.0, including expressions that return scalar values.
