这是我到目前为止所做的（当然我在网上找到了代码）

<?php 

// ----------------  The example uses the php 5 "DOM Functions"  to select specific node uding Xpath query ------------------  

$doc = new DOMDocument;                                        // Create a new dom document 
$doc->preserveWhiteSpace = false;                              // Set features 
$doc->formatOutput = true;                                     // Create indents on xml 

$doc->Load('Teva_Footwear-Teva_Footwear_Product_Catalog.xml');                                        // Load the file 

$xpath = new DOMXPath($doc); 
$query = '//catalog/product/sku[. = "1000183-WAL"]';         // The xpath (starts from root node) 
$names = $xpath->query($query);                                 // A list of matched elements 

$Output=""; 
foreach ($names as  $node) { 
   $Output.=$doc->saveXML($node->parentNode)."\n";             // We get the parent of  "<firstname>" element  (the entire "<person>" node and its children) (maybe get 

the parent node directly using xpath) 
                                                                // and use the saveXML() to convert it to string   
} 


echo $Output."<br>\n\n";                                      // The result  

echo "<hr><br><b>Below view the results  as HTML content. &nbsp; (See also the page's HTML code):</b>\n<pre>".htmlspecialchars($Output)."</pre>"; 

?>

这是此代码之后的输出：（由制造商ID选择的记录）

它如何显示我想要的记录的全部内容是这样的，所以我可以根据我的需要进行格式化。元价格描述中的关键字和由购买网址链接的照片，例如<a href="$buyurl"><img src="$image_url"></a>

使用 simplexml 的解决方案：

$xml = simplexml_load_file('file.xml');

list($product) = $xml->xpath("//product[sku = '1000183-WAL']");

echo "<a href=\"{$product->imageurl}\"><img src=\"{$product->imageurl}\" /></a>";
