根据下拉选择显示其余XML文件项属性

I have an XML file. I need on "Grad" selection to show values from Firma and BrojTelefona attributes, somewhere on the right side of Option list. As text.

HTML:

<html>
<form method="post" action="">
    <?php
    echo "<select>";
        $xml = simplexml_load_file('adler.xml');
            foreach ($xml->record as $item)
            {
                 echo "<option value='".$item->Grad."'>" . $item->Grad . "</option>";
            }
    echo "</select>";
    ?>
</form>
</html>

My XML file:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<data-set xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <record>
        <Firma>TD electronic</Firma>
        <BrojTelefona>034 715 445</BrojTelefona>
        <Grad>Arandjelovac</Grad>
    </record>
    <record>
        <Firma>Lihno d.o.o.</Firma>
        <BrojTelefona>011 848 5705</BrojTelefona>
        <Grad>Batajnica</Grad>
    </record>

    I have found solution.

     <html>
<head>
<script>
function show(str) {
  if (str=="") {
    document.getElementById("txtHint").innerHTML="";
    return;
  } 
  if (window.XMLHttpRequest) {
    // code for IE7+, Firefox, Chrome, Opera, Safari
    xmlhttp=new XMLHttpRequest();
  } else {  // code for IE6, IE5
    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
  xmlhttp.onreadystatechange=function() {
    if (this.readyState==4 && this.status==200) {
      document.getElementById("txtHint").innerHTML=this.responseText;
    }
  }
  xmlhttp.open("GET","get.php?q="+str,true);
  xmlhttp.send();
}
</script>
</head>
<body>
<form>
    <?php
     echo '<select onchange="show(this.value)">';
        $xml = simplexml_load_file('adler.xml');
            foreach ($xml->record as $item)
            {
                 echo "<option value='".$item->Grad."'>" . $item->Grad . "</option>";
            }
    echo "</select>";
    ?>
</form>
<div id="txtHint"><b>Servis Adler uređaja za </b></div>
</body>
</html>

    And get.php file

    <?php
 $q=$_GET["q"];

 $xmlDoc = new DOMDocument();
 $xmlDoc->load("adler.xml");

$x=$xmlDoc->getElementsByTagName('Grad');

for ($i=0; $i<=$x->length-1; $i++) {
  //Process only element nodes
  if ($x->item($i)->nodeType==1) {
    if ($x->item($i)->childNodes->item(0)->nodeValue == $q) {
      $y=($x->item($i)->parentNode);
    }
  }
}

$record=($y->childNodes);

for ($i=0;$i<$record->length;$i++) { 
  //Process only element nodes
  if ($record->item($i)->nodeType==1) {
    echo("<b>" . $record->item($i)->nodeName . ":</b> ");
    echo($record->item($i)->childNodes->item(0)->nodeValue);
    echo("<br>");
  }
}
?>
