Don't parse HTML with regular expressions. Read.

$html = '
 <dt class="gallery-icon">
    <a href="?attachment_id=31" title="title">
        <img width="150" height="150" src="librosdefirmas-bodas-1-150x150.jpg" class="attachment-thumbnail" alt="Caption">
    </a>
</dt>
';
$dom_document = new DOMDocument();
$dom_document->loadHTML($html);
$dom_xpath = new DOMXpath($dom_document);
$elements = $dom_xpath->query("//dt/a");
print_r( $elements->item(0)->getAttribute('title') );

The ".*" is a greedy match, i.e. it'll wander outside of the first quote if there is a later one that it can match. Use [^"]* instead of .* to match all characters but a quote.
