Getting individual information from XML array

[soneen]

Mods, sorry for the double post, but I realized this is more of a PHP question than an XML question! I am trying to pull the individual pieces out of an xml array here is my php to get the xml:

PHP Code:

$url="http://api.campusbooks.com/11/rest/bookprices?key=bleh&isbn=9780132080231"; 

$response = file_get_contents($url); 
$parsed_xml = simplexml_load_string($response); 

var_dump($parsed_xml); 


And here is my XML (as shown by the var_dump):

object(SimpleXMLElement)#1 (3) {
  ["@attributes"]=>
  array(2) {
    ["status"]=>
    string(2) "ok"
    ["version"]=>
    string(2) "11"
  }
  ["label"]=>
  object(SimpleXMLElement)#2 (1) {
    ["@attributes"]=>
    array(2) {
      ["plid"]=>
      string(4) "3670"
      ["name"]=>
      string(11) "Website"
    }
  }
  ["page"]=>
  object(SimpleXMLElement)#3 (3) {
    ["@attributes"]=>
    array(1) {
      ["name"]=>
      string(10) "bookprices"
    }
    ["book"]=>
    object(SimpleXMLElement)#4 (13) {
      ["isbn10"]=>
      string(10) "0132080230"
      ["isbn13"]=>
      string(13) "9780132080231"
      ["title"]=>
      string(28) "Microeconomics (7th Edition)"
      ["author"]=>
      string(33) "Robert Pindyck - Daniel Rubinfeld"
      ["binding"]=>
      string(9) "Hardcover"
      ["msrp"]=>
      string(6) "166.67"
      ["pages"]=>
      string(3) "768"
      ["publisher"]=>
      string(13) "Prentice Hall"
      ["published_date"]=>
      string(10) "2008-06-21"
      ["edition"]=>
      string(1) "7"
      ["rank"]=>
      string(5) "58345"
      ["rating"]=>
      string(3) "3.5"
      ["image"]=>
      string(60) "http://ecx.images-amazon.com/images/I/51GLbJmZclL._SL75_.jpg"
    }

So what is the syntax to pull out book=>edition and echo it for example? I am really struggling with this.

It'd be easy if you give the contents of the xml file instead of var_dump() result
