Formating xml results passed from a php parser script

[suzy_Q]

Hi guys,
How can i format my results when parsing xml to PHP?
At the moment the value for $data is not formated.
I was wanting to put line breaks after each <slide>.
Here is the xml file:

<presentations id="root">
   <presentation>
     <slide>
       <name>Picture 1</name>
       <jpegurl>images/pic_1.swf</jpegurl>
     </slide>
     <slide>
       <name>Picture 2</name>
       <jpegurl>images/pic_2.swf</jpegurl>
     </slide>
     <slide> 
       <name>Picture 3</name> 
       <jpegurl>images/pic_3.swf</jpegurl>
     </slide>
     <slide> 
       <name>Picture 4</name> 
       <jpegurl>images/pic_4.swf</jpegurl>
     </slide>
     <slide> 
       <name>Picture 5</name> 
       <jpegurl>images/pic_5.swf</jpegurl>
     </slide>
     <slide> 
       <name>Picture 6</name> 
       <jpegurl>images/pic_6.swf</jpegurl>
     </slide>
     <slide> 
       <name>Picture 7</name> 
       <jpegurl>images/pic_7.swf</jpegurl>
     </slide>
     <slide> 
       <name>Picture 8</name> 
       <jpegurl>images/pic_8.swf</jpegurl>
     </slide>
     <slide> 
       <name>Picture 9</name> 
       <jpegurl>images/pic_9.swf</jpegurl>
     </slide>
   </presentation>
</presentations> 

and here is the php parser code:

<?
$xml_file = "xml/images.xml";
?>
<title>Ford - Image Viewer</title>
   
<p><b>Welcome to FORD Image Viewer - Administration</b><br>
------------------------------------------------------</p><br>

<table width="750" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td width="150" bgcolor="#CCCCCC"><font size="1" face="Verdana, Arial, Helvetica, sans-serif"><strong>&nbsp;&nbsp;SLIDE 
      NAME</strong></font></td>
    <td width="300" bgcolor="#CCCCCC"><font size="1" face="Verdana, Arial, Helvetica, sans-serif"><strong>&nbsp;&nbsp;IMAGE 
      FILE NAME</strong></font></td>
    <td width="300">&nbsp;&nbsp;<img src="add_button.jpg" width="60" height="20" align="middle"></td>
  </tr>
</table>
 
<?

function characterData($parser_instance, $xml_data) {    
echo "$xml_data"; 
}
 
$parser = xml_parser_create();
 
xml_set_character_data_handler($parser, "characterData");
if (!($filehandler = fopen($xml_file, "r"))) {    
die("could not open XML input"); 
}
while ($data = fread($filehandler, 4096)) {    
if (!xml_parse($parser, $data, feof($filehandler))) {        
die(sprintf("XML error: %s at line %d",                    
xml_error_string(xml_get_error_code($parser)),                    
xml_get_current_line_number($parser)));    
} 
}
fclose($filehandler); 
xml_parser_free($parser);
echo "</table>";
?>

Any comments greatly appreciated.

Cheers,
Suzy
