remove HTML tag by content - php

Question

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...

Answer 1

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);
}
?>

Answer 2

Regex and replace:
$var = '<table>
<tr>
<td width="50">Ã</td>
<td>My interssing content</td>
<td width="50">Ã</td>
</tr>
<table>';
$final = preg_replace('#(<td width="50".*?>).*?(</td>)#', '$1$2', $var);
$final = str_replace('<td width="50"></td>', '', $final);
echo $final;
