Question

我正在尝试用ebay解析用于finditem api的XML响应。这是我的代码：

<head>
    <title>Title</title>
    <meta content="text/html;charset=utf-8" http-equiv="Content-Type">
    <meta content="utf-8" http-equiv="encoding">
    <meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<?

$pagenumber = 1;
$keyword = 'iphone';
$entriesperpage = 1;
$ebayusername = 'ebay-username-here';

$response = getFindProducts($keyword, $ebayusername, $entriesperpage);
echo '<div style="display: none;">' . $response . '</div>';

$xmlResponse = new SimpleXMLElement($response);
echo $xmlResponse -> searchresult -> item[0] -> title;

function getFindProducts($keyword,$ebayusername,$entriesperpage) {

$xmlRequest = "<?xml version=\"1.0\" encoding=\"utf-8\"?>";
$xmlRequest .= '<findItemsAdvancedRequest xmlns="http://www.ebay.com/marketplace/search/v1/services">';
$xmlRequest .= '<keywords>' . $keyword . '</keywords>';
$xmlRequest .= '<itemFilter>';
$xmlRequest .= '<name>Seller</name>';
$xmlRequest .= '<value>' . $ebayusername . '</value>';
$xmlRequest .= '</itemFilter>';
$xmlRequest .= '<paginationInput>';
$xmlRequest .= '<entriesPerPage>' . $entriesperpage . '</entriesPerPage>';
$xmlRequest .= '</paginationInput>';
$xmlRequest .= '</findItemsAdvancedRequest>';

// define our header array for the Shopping API call
$headers = array(
    'X-EBAY-SOA-SECURITY-APPNAME:' . 'appname-here',
    'X-EBAY-SOA-OPERATION-NAME:findItemsAdvanced'
);

// initialize our curl session
$session  = curl_init(FINDING_API_ENDPOINT);

// set our curl options with the XML request
curl_setopt($session, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($session, CURLOPT_HTTPHEADER, $headers);
curl_setopt($session, CURLOPT_POST, true);
curl_setopt($session, CURLOPT_POSTFIELDS, $xmlRequest);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);

if(curl_exec($session) === false){ echo 'Curl error: ' . curl_error($session); }

// execute the curl request
$responseXML = curl_exec($session);

// close the curl session
curl_close($session);

// return the response XML
return $responseXML;

}

?>
</body>

</html>

当我运行它时，它成功运行，因为它确实从ebay获得响应，如果我在源代码中回显整个页面，我可以看到产品XML结构。

问题出在以下部分：

$xmlResponse = new SimpleXMLElement($response);
echo $xmlResponse -> searchresult -> item[0] -> title;

它无声地失败而没有任何错误。我确实打开了错误报告。

非常感谢任何帮助！

最后破解了它。经过几个小时的挫折后，终于发现xml回声路径 case sensative 。只是发生在实际的脚本中，因为当我从html源代码复制xml（对于上面的例子）时，它显示了所有小写。但实际返回的xml在xml节点中具有混合大小写。

所以，

    echo $xmlResponse -> searchresult -> item[0] -> title;

需要：

    echo $xmlResponse -> searchResult -> item[0] -> title;
