 <?php
                $xml = simplexml_load_file("agent.xml") or die("Error: Cannot create object");
                foreach($xml as $agent){
                function processXML($node){
                    foreach($node->children() as $agent => $data){
                        $agent= trim($agent);   
                        if($agent=='image')
                        {
                            echo '<div><img src="'.$data.'" ></div>';
                            echo '<div>';
                            echo '</div>';
                        }
                        elseif($agent=='id')
                        {
                             echo '<div class = "Left">';
                             echo '<input type = "button" name="Agent" id = "'.$data.'" class = "subs-btn" value = "Select this Agent" OnClick = Selected(this.id);>';
                             echo '</div>';
                             echo '<br/>';
                             echo '<br/>';  
                        }
                        else
                        {
                            echo '<div class = "inline1">';
                            echo $data;
                            echo '</div>';
                            echo '<br/>';

                        }
                            processXML($data);
                        }           

                    }  
                processXML($xml);
                }

use xpath to select the <agent> with the desired <id>:

$agent = $xml->xpath("/agents/agent[id='1']");

if (isset($agent[0])) $agent = $agent[0]; else $agent = NULL;
echo $agent->name;
