Question handling xml data

Posted on 16th Feb 2014 by admin

Hello,

I have sucessfull followed this tutorial
http://www.phpfreaks.com/tutorial/handling-xml-data

and used xpath to find the books I need, here is my code

Code: [Select]<?php
// load SimpleXML
$books = new SimpleXMLElement('books.xml', null, true);

echo <<<EOF
<table>
<tr>
<th>Title</th>
<th>Author</th>
<th>Publisher</th>
<th>Price at Amazon.com</th>
<th>ISBN</th>
</tr>

EOF;
foreach($books->xpath('book1/book') as $book) // loop through our books
{
echo <<<EOF
<tr>
<td>{$book->title}</td>
<td>{$book->author}</td>
<td>{$book->publisher}</td>
<td>${$book->amazon_price}</td>
<td>{$book['isbn']}</td>
</tr>

EOF;
}
echo '</table>';
?>

now I want to only show the first 5 books in the xml file as it is updated regularly

I can't seem to figure out how to do this.

any help would be great , thanks
