如何从标记名称开头有“@”的xml获取值？

Question

I'm trying to get values from a XML file, but I have a problem. One of tag name starts with "@". So I'm getting an error on that.

This is my xml

object(SimpleXMLElement)#537 (1) { ["urun"]=> array(5225) { [0]=> object(SimpleXMLElement)#547 (1) { ["@attributes"]=> array(7) { ["id"]=> string(4) "2972" ["secenekid"]=> string(1) "4" ["grup"]=> string(4) "YAŞ" ["ozellik"]=> string(1) "1" ["fiyat"]=> string(1) "0" ["agirlik"]=> string(1) "0" ["Stok"]=> string(1) "0" } } [1]=> object(SimpleXMLElement)#548 (1) { ["@attributes"]=> array(7) { ["id"]=> string(4) "2972" ["secenekid"]=> string(1) "5" ["grup"]=> string(4) "YAŞ" ["ozellik"]=> string(1) "2" ["fiyat"]=> string(1) "0" ["agirlik"]=> string(1) "0" ["Stok"]=> string(1) "0" } } 

I'm trying to get like that.

$url = "http://xx.com";
$xml = simplexml_load_file($url);

foreach($xml->urun->@attributes as $val) {
echo $val->id; 
}

and this is the error what I see

syntax error, unexpected '@', expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$'

so what should I do know for to solve that?

Thanks.

The curly braces syntax can be used to access such properties:

$xml->urun->{'@attributes'}

See PHP curly brace syntax for member variable

In this case you could also use $xml->urun->attributes(), see Accessing @attribute from SimpleXML
