How do i filter the output of a scrapper? (PHP) : <p>I am scrapping a page and i am getting this result:</p>

<pre><code>string(1) " "
string(15) " +0,25 pist.wit"
string(14) " +0,25 pist.br"
// and so on...
</code></pre>

<p>But i want a result like this:</p>

<pre><code>0,25
0,25
//and so on...
</code></pre>

<p>So technically i want to filter the prices (without + signs) and 
the bread names (pist.wit etc.)
Does someone know how to do this? Here is my code:</p>

<pre><code> public function onRun()
{
    $client = new Client();
    $crawler = $client-&gt;request('GET', 'http://www.sandwich-express.nl/online-bestellen/');
    $crawler-&gt;filter('tr')-&gt;each(function ($node) {
        if(sizeof($node-&gt;filter('.table-spacing')) &gt; 0)
            var_dump('nieuwe headers next TR');
        $node-&gt;filter('tr.colomn_text td')-&gt;each(function ($node) {
            var_dump($node-&gt;text());
        });
    });

}
</code></pre>
