cannot access SimpleXML object property

Hi,

I am working with an XML document and have a SimpleXML object whose =
var_dump looks like this:

---
object(SimpleXMLElement)#2 (10) {
["@attributes"]=3D>
array(1) {
["id"]=3D>
string(7) "3854857"
}
["type"]=3D>
string(7) "Article"
["createDate"]=3D>
string(25) "2006-09-06T16:42:20-07:00"
["editDate"]=3D>
string(25) "2007-07-16T09:15:53-07:00"
["creator"]=3D>
string(19) "Michael Gottfredson"
["status"]=3D>
string(5) "ready"
["field"]=3D>
...snip a bunch of stuff...
}
---

Assuming the above object is referenced by $current_object, I can access =
the values of most stuff with $current_object->creator or whatever. =
However, I cannot figure out how to access the value of id. I tried the =
following, none of which worked for me:

1. $current_object->@attributes->id (gives Parse error: syntax error, =
unexpected '@', expecting T_STRING or T_VARIABLE or '{' or '$' in =
/Applications/apache/htdocs/test.php on line 33)

2. $current_object->'@attributes'->id (gives Parse error: syntax error, =
unexpected T_CONSTANT_ENCAPSED_STRING, expecting T_STRING or T_VARIABLE =
or '{' or '$' in/Applications/apache/htdocs/test.php on line 33)

3. $current_object->{@attributes}->id (no error but is null)

4. $current_object->{'@attributes'}->id (no error but is also null)

Does anyone know how I can reference the value of id? Thanks!
