I have e.g. this xml parse script:

<?
$xml = simplexml_load_file("books.xml");

foreach($xml->Book as $Book) {
echo "
<p><strong>".$Book->BookTitle."</strong><br>
<em>by ".$Book->BookAuthor."</em><br>
(Published by ".$Book->BookPublisher.",
ISBN: ".$Book->BookISBN.")<br>
<font color=red>price/font> \$".$Book->BookPrice."</p>
<hr noshade>";
}

?>
If I want to get the xml from this web site instead: http://www.dailymail.co.uk/pages/xml...n_page_id=1779

Is it possible to exclude xml using the script?
e.g.
<title>the Mail online | Football</title>
<description>Team news, match analysis and transfer gossip</description>
<link>http://www.dailymail.co.uk/pages/live/sport/football.html?in_page_id=1779&amp;ito=1490</link>
Wich is a constant, that never changes text..

My question is, how can I use a XML parser, and exclude some of the stuff in the xml feed? What code can I use for that?
