I have this table in output from a program (string converted in a DomDocument in PHP):

<table>
    <tr>
        <td width="50">Â </td>
        <td>My content</td>
        <td width="50">Â </td>
    </tr>
<table>

I need to remove the two tag <td width="50">Â </td> (i don't know why the program adds them, but there are -.-") like this:

<table>
    <tr>
        <td>My content</td>
    </tr>
<table>

What's the best way for do it in PHP?

Edit: the program is JasperReport Server. I call the report rendering function via web application:

//this is the call to server library for generate the report
$reportGen = $reportServer->runReport($myReport);

$domDoc = new \DomDocument();
$domDoc->loadHTML($reportGen);
return $domDoc->saveHTML($domDoc->getElementsByTagName('table')->item(0));

return the upper table who i need to fix...

    Try this

    <?php
        $domDoc = new DomDocument();
        $domDoc->loadHTML($reportGen);
        $xpath = new DOMXpath($domDoc);
        $tags = $xpath->query('//td');
        foreach($tags as $tag) {
            $value = $tag->nodeValue;
            if(preg_match('/^(Â )/',$value))
            $tag->parentNode->removeChild($tag);
        }
    ?>
