[jurena]

No lo he probado:

Código php:

<?php
include "conexion.php"; 
$sent="(SELECT id, nom, direc, cont FROM live) UNION ALL (select id, nom direc, cont FROM live2) ORDER BY cont"; 
$res = mysql_query($sent, $conn); 
while($row = mysql_fetch_array($res)){?>   
<linea blog="<?php echo $row['nom'];?>" direccion="<?php echo $row['direc'];?>"/> 
<?php
}   
?>
