用php解析格式奇怪的xml

Question

这里是 xml 的 sn-p，它是我从未见过的格式，在我的一生中，我无法弄清楚如何将它解析成在网站上看起来确实不错的东西。这是xml。这是在 shopping.com api 上搜索查询的结果。

object(SimpleXMLElement)#14 (11) {
  ["@attributes"]=>
  array(1) {
    ["id"]=>
    string(9) "101677489"

  string(26) "Nikon D3100 Digital Camera"
  ["shortDescription"]=>
  string(87) "14.2 Megapixel, SLR Camera, 3 in. LCD Screen, With High Definition Video, Weight: 1 lb."

有什么想法吗？我已经尝试过下面的代码，但它并没有改变任何东西。

foreach( $xml->categories->category->items->product as $product )
{
var_dump($product);
}
foreach( $xml->categories->category->items->offer as $offer )
{
var_dump($offer);
}

Answer 1

尝试类似：

foreach( $xml->categories->category->items->product as $product )
{
    echo "{$product->name} from {$product->minPrice} to {$product->maxPrice}\n";
}
