PHP XML数据解析代码

//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 />'; 
}
