Generate XML based on MySQL Query

Hello guys,

I need to create a XML file like this one(same structure) but based on MySQL query:

<chart>

   <chart_type>pie</chart_type>

   <chart_data>
      <row>
         <null/>
         <string>2007</string>
         <string>2008</string>
         <string>2009</string>
      </row>
      <row>
         <string>Region A</string>
         <number>10</number>
         <number>30</number>
         <number>63</number>
      </row>
   </chart_data>


</chart>

I found a couple of good articles but I do not know how to get the same structure, I tried this:

<?php

header("Content-type: text/xml");

$host = "localhost";
$user = "test";
$pass = "test";
$database = "test";

$enlace = mysql_connect($host, $user, $pass) or die("Error MySQL.");
mysql_select_db($database, $enlace) or die("Error base de datos.");

$query = "SELECT AGENTE, count(*) FROM clientes group by agente";
$resultado = mysql_query($query, $enlace) or die("Sin resultados.");

$salida_xml = "<?xml version=\"1.0\"?>\n";

$salida_xml .= "<chart>\n";
$salida_xml .= "<chart_type>" . 'pie' . "</chart_type>\n";
    $salida_xml .= "<chart_data>\n";
    for($x = 0 ; $x < mysql_num_rows($resultado) ; $x++){
        $fila = mysql_fetch_assoc($resultado);
        $salida_xml .= "\t<row>\n";
        $salida_xml .= "\t\t<agente>" . $fila['AGENTE'] . "</agente>\n";
        $salida_xml .= "\t\t<cantidad>" . $fila['count(*)'] . "</cantidad>\n";
            // Corregiendo caracteres incorrectos
            $fila['texto'] = str_replace("&", "&", $fila['texto']);
            $fila['texto'] = str_replace("<", "&lt;", $fila['texto']);
            $fila['texto'] = str_replace(">", "&gt;", $fila['texto']);
           // $salida_xml .= "\t\t<texto>" . $fila['texto'] . "</texto>\n";
        $salida_xml .= "\t</row>\n";
    }//segundo for
    $salida_xml .= "</chart_data>\n";


$salida_xml .= "</chart>";

echo $salida_xml;

but I'm not getting the same structure, I am getting this:

<chart>
<chart_type>pie</chart_type>
−
<chart_data>
<row>
       
    </row>
−
<row>
<agente>Danilo</agente>
<cantidad>8</cantidad>
</row>
<row>
       
    </row>
−
<row>
<agente>Evelyn</agente>
<cantidad>5</cantidad>
</row>
<row>
       
    </row>
−
<row>
<agente>Maribel</agente>
<cantidad>2</cantidad>
</row>
<row>
       
    </row>
−
<row>
<agente>Nestor</agente>
<cantidad>11</cantidad>
</row>
<row>
       
    </row>
−
<row>
<agente>Noemy</agente>
<cantidad>2</cantidad>
</row>
</chart_data>
</chart>

Can someone give me a hand plase?


Thanks in advance

Doing some extra research I almost get to the result that I need, I guess I am jus

t having an small problem.

Basically I need this

[PHP]
<chart>

   <chart_type>pie</chart_type>

   <chart_data>
      <row>
         <null/>
         <string>2007</string>
         <string>2008</string>
         <string>2009</string>
      </row>
      <row>
         <string>Region A</string>
         <number>10</number>
         <number>30</number>
         <number>63</number>
      </row>
   </chart_data>
</chart>
[/PHP]

Currently I have this:

[PHP]
<chart>
    <chart_type>pie</chart_type>

    <chart_data>
        <row>
            <null></null>
            <agente>Danilo</agente>
            <agente>Evelyn</agente>

            <agente>Maribel</agente>
            <agente>Nestor</agente>
            <agente>Noemy</agente>
        </row>
        <row>
            <rutas>rutas</rutas>
            <cantidad></cantidad>

            <cantidad></cantidad>
            <cantidad></cantidad>
            <cantidad></cantidad>
            <cantidad></cantidad>
        </row>
    </chart_data>
</chart>
[/PHP]

And I am using this code

[PHP]<?php

header("Content-type: text/xml");

$host = "xxx";
$user = "xxxx";
$pass = "xxxx";
$database = "xxxx";

$enlace = mysql_connect($host, $user, $pass) or die("Error MySQL.");
mysql_select_db($database, $enlace) or die("Error base de datos.");

$query = "SELECT AGENTE, count(*) FROM clientes WHERE PREVENTA LIKE 'Viernes' group by agente";
$resultado = mysql_query($query, $enlace) or die("Sin resultados.");

$salida_xml = "<?xml version=\"1.0\"?>\n";

$salida_xml .= "<chart>\n";
$salida_xml .= "\t<chart_type>" . 'pie' . "</chart_type>\n\n";
$salida_xml .= "\t<chart_data>\n";
            $salida_xml .= "\t\t<row>\n";
            $salida_xml .= "\t\t\t<null>" . $fila5['NULL']. "</null>\n";
            for($y = 0 ; $y < mysql_num_rows($resultado) ; $y++){
                $fila2 = mysql_fetch_assoc($resultado); 
                $salida_xml .= "\t\t\t<agente>" . $fila2['AGENTE'] . "</agente>\n";
                }//cierro for Y
            $salida_xml .= "\t\t</row>\n";
            $salida_xml .= "\t\t<row>\n";    
            $salida_xml .= "\t\t\t<rutas>" . 'rutas'. "</rutas>\n";
            for($z = 0 ; $z < mysql_num_rows($resultado) ; $z++){
                $valor = mysql_fetch_assoc($resultado);
                $salida_xml .= "\t\t\t<cantidad>" . $valor['count(*)'] . "</cantidad>\n";
            }//cierro for z

            $salida_xml .= "\t\t</row>\n";
    $salida_xml .= "\t</chart_data>\n";
   
$salida_xml .= "</chart>";

echo $salida_xml;

?>[/PHP]

The issue I am having is that it is not showing the quantity, in this case "cantidad", does someone know why?
