Ok im working on a xml parser just like this one

<?php

$xml_file = "News.xml";

$xml_headline_key = "*NEWS*STORY*HEADLINE";
$xml_description_key = "*NEWS*STORY*DESCRIPTION";

$story_array = array();

$counter = 0;
class xml_story{
    var $headline, $description;
}

function startTag($parser, $data){
    global $current_tag;
    $current_tag .= "*$data";
}

function endTag($parser, $data){
    global $current_tag;
    $tag_key = strrpos($current_tag, '*');
    $current_tag = substr($current_tag, 0, $tag_key);
}

function contents($parser, $data){
    global $current_tag, $xml_headline_key, $xml_description_key, $counter, $story_array;
    switch($current_tag){
        case $xml_headline_key:
            $story_array[$counter] = new xml_story();
            $story_array[$counter]->headline = $data;
            break;
        case $xml_description_key:
            $story_array[$counter]->description = $data;
            $counter++;
            break;
    }
}

$xml_parser = xml_parser_create();

xml_set_element_handler($xml_parser, "startTag", "endTag");

xml_set_character_data_handler($xml_parser, "contents");

$fp = fopen($xml_file, "r") or die("Could not open file");

$data = fread($fp, filesize($xml_file)) or die("Could not read file");

if(!(xml_parse($xml_parser, $data, feof($fp)))){
    die("Error on line " . xml_get_current_line_number($xml_parser));
}

xml_parser_free($xml_parser);

fclose($fp);

?>

<html>
<head>
<title>NEWS</title>
</head>
<body bgcolor="#FFFFFF">
<?php
for($x=0;$x<count($story_array);$x++){
    echo "\t<h2>" . $story_array[$x]->headline . "</h2>\n";
    echo "\t\t\n";
    echo "\t<i>" . $story_array[$x]->description . "</i>\n";
}
?>

</body>
</html>

Now what i need is a function that will find a exact value in the headline I was thinking of using in_array so if it matches then it would grab it then somehow remove it from the array then unshift and place it at the very top of the array.

What im trying to do is just find a exact value then if it exists move it to the very top of the array.

What would be the best way to go about doing this?
