Hello! I try to use amazon API using PHP. If I use

print_r($parsed_xml->Items->Item->ItemAttributes)

it show me some result like

SimpleXMLElement Object ( [Binding] => Electronics [Brand] => Canon [DisplaySize] => 2.5 [EAN] => 0013803113662 [Feature] => Array ( [0] => High-powered 20x wide-angle optical zoom with Optical Image Stabilizer [1] => Capture 720p HD movies with stereo sound; HDMI output connector for easy playback on your HDTV [2] => 2.5-inch Vari-Angle System LCD; improved Smart AUTO intelligently selects from 22 predefined shooting situations [3] => DIGIC 4 Image Processor; 12.1-megapixel resolution for poster-size, photo-quality prints [4] => Powered by AA batteries (included); capture images to SD/SDHC memory cards (not included) ) [FloppyDiskDriveDescription] => None [FormFactor] => Rotating [HasRedEyeReduction] => 1 [IsAutographed] => 0 [IsMemorabilia] => 0 [ItemDimensions] => SimpleXMLElement Object ( [Height] => 340 [Length] => 490 [Weight] => 124 [Width] => 350 ) [Label] => Canon [LensType] => Zoom lens [ListPrice] => SimpleXMLElement Object ( [Amount] => 60103 [CurrencyCode] => USD [FormattedPrice] => $601.03 ) [Manufacturer] => Canon [MaximumFocalLength] => 100 [MaximumResolution] => 12.1 [MinimumFocalLength] => 5 [Model] => SX20IS [MPN] => SX20IS [OpticalSensorResolution] => 12.1 [OpticalZoom] => 20 [PackageDimensions] => SimpleXMLElement Object ( [Height] => 460 [Length] => 900 [Weight] => 242 [Width] => 630 ) [PackageQuantity] => 1 [ProductGroup] => Photography [ProductTypeName] => CAMERA_DIGITAL [ProductTypeSubcategory] => point-and-shoot [Publisher] => Canon [Studio] => Canon [Title] => Canon PowerShot SX20IS 12.1MP Digital Camera with 20x Wide Angle Optical Image Stabilized Zoom and 2.5-inch Articulating LCD [UPC] => 013803113662 )
