How to catch XML Dom with php regex

I got some XML Atom files on local. On all of those files, there are some <author>...</author> balise that I want to catch in a PHP string variable.

So I did that : 

function parseAtomByBalise($xml,$balise) {
    $arrayStr=array();
    preg_match('#<'.$balise.'>(.*)</'.$balise.'>#',$xml,$arrayStr);

    return $arrayStr;
}
 $fxml=fopen($xml,'r');
    $strXML=fgets($fxml);
    echo '<p>author: <textarea>';
    $authors=parseAtomByBalise($strXML,'author');
    foreach($authors as $author) {
        if($author!=$strXML)
            echo $author.'\n';
    }
    echo '</textarea></p>';
}

Files are opening, and strXML is the good string. I got some stranges behaviours of preg_match, that makes me think that this is not the good function... I got more balises than only the balises insides <author></author>

How should I do ?

  1. Don't try to reinvent the wheel.
  2. Regex is not good for parsing XML(just an example, not the absolute proof, but...)
  3. use the PHP built in tools like simple XML
