//xml string
$xml_string="<?xml version=1.0?>
<users>
<user id=398>
<name>Foo</name>
<email>foo@bar.com</name>
</user>
<user id=867>
<name>Foobar</name>
<email>foobar@foo.com</name>
</user>
</users>";

//load the xml string using simplexml
$xml = simplexml_load_string($xml_string);

//loop through the each node of user
foreach ($xml->user as $user)
{
//access attribute
echo $user[id], ;
//subnodes are accessed by -> operator
echo $user->name, ;
echo $user->email, <br />;
