Problemas con mysql_db_query

[privatefta]

tengo esta función

Código PHP:

<?php
 
$dbhost = "localhost";
$dbname = "panel";
$dbuser = "panel";
$dbpass = "panellenap";
 
$conn = @mysql_connect($dbhost,$dbuser,$dbpass) or die ("ERROR! No connection to database!");
mysql_select_db($dbname, $conn);
$usql = mysql_query("SELECT * FROM usuarios WHERE posicion='1' ORDER BY id_usuario ASC");
 
print("<xml-user-manager ver=\"1.0\">\n");
while($line=mysql_fetch_array($usql)) {
    if ($line["usuario"] == "") {
        $usuario = "";
    } else {
        $usuario = "name=\"".$line["usuario"]."\" ";
    }
    
    if ($line["contrasena"] == "") {
        $contrasena = "";
    } else {
        $contrasena = "password=\"".$line["contrasena"]."\" ";
    }
    
    if ($line["profiles"] == "") {
        $profiles = "";
    } else {
        $profiles = "profiles=\"".$line["profiles"]."\" ";
    }
    
    if ($line["maxconnections"] == "") {
        $maxconnections = "";
    } else {
        $maxconnections = "max-connections=\"".$line["maxconnections"]."\" ";
    }
    
    if ($line["enabled"] == "") {
        $enabled = "";
    } else {
        $enabled = "enabled=\"".$line["enabled"]."\" ";
    }
    
    if ($line["mapexclude"] == "") {
        $mapexclude = "";
    } else {
        $mapexclude = "map-exclude=\"".$line["mapexclude"]."\" ";
    }
    
    if ($line["debug"] == "") {
        $debug = "";
    } else {
        $debug = "debug=\"".$line["debug"]."\" ";
    }
    
    print("<user ".$usuario.$contrasena.$profiles.$maxconnections.$enabled.$mapexclude.$debug."/>\n");
}
print("</xml-user-manager>");
mysql_close($conn);
?>
