limit search results

[optikalefx]

ive got this code so far for a live search, which does work

<?php
$xmlDoc = new DOMDocument();
$xmlDoc->load("links.xml");
$x=$xmlDoc->getElementsByTagName('link');//get the q parameter from URL
$q=$_GET["q"];//lookup all links from the xml file if length of q>0
if (strlen($q) > 0)
{
$hint="";
for($i=0; $i<($x->length); $i++)
{
$y=$x->item($i)->getElementsByTagName('title');
$z=$x->item($i)->getElementsByTagName('url');
if ($y->item(0)->nodeType==1)
  {
  //find a link matching the search text
  if (stristr($y->item(0)->childNodes->item(0)->nodeValue,$q))
   {
   if ($hint=="")
    {
    $hint="<a href='" . 
    $z->item(0)->childNodes->item(0)->nodeValue . 
    "' target='_blank'>" . 
    $y->item(0)->childNodes->item(0)->nodeValue . "</a>";
    }
   else
    {
    $hint=$hint . "<br /><a href='" . 
    $z->item(0)->childNodes->item(0)->nodeValue . 
    "' target='_blank'>" . 
    $y->item(0)->childNodes->item(0)->nodeValue . "</a>";
    }
   }
  }
}
}// Set output to "no suggestion" if no hint were found
// or to the correct values
if ($hint == "")
{
$response="no suggestion";
}
else
{
$response=$hint;
}//output the response
echo $response;
?>

 

 

on the tutorial site it says for purpose of demonstration they limit their search results to 8.  on my exmample i get much more than 8.  How can i add a parameter here so it only grabs 8?

Change

for($i=0; $i<($x->length); $i++)

 

To

 

for($i=0; $i<8; $i++)

i tried that, that just limits how many letters of the word it searches.  It gave me 10 results when I changed that parameter.

 

Whats happening is that it grabs every <title> from the xml document, and then searches within those characters.  So I gotta find a way to limit how many <title>s it grabs
