PHP XMLReader xml：lang

Question

如何从此xml文件读取xml：lang值？

<Catalog><Products> 
 
<Product> 
 
<Id>123</Id> 
 
<Name xml:lang="en">name english product</Name> 
 
<Description xml:lang="en">desc xyz</Description> 
 
<Name xml:lang="de">name german</Name> 
 
<Description xml:lang="de">desc germa</Description> 
 
<Image num="1"><Url>pic.jpg</Url></Image> 
 
<Image num="2"><Url>pic2.jpg</Url></Image> 
 
</Product> 
 
<Product>...

我想要的XML值：LANG = “德” - 标签和图像值。 有没有人有想法？ Thanx :-)

更新：我解析这样的XML，但我怎么得到这个值？

$datei = "test.xml"; 
 
$z = new XMLReader; 
 
$z->open($datei); 
 
\t 
 
$doc = new DOMDocument; 
 
\t 
 
while ($z->read() && $z->name !== 'Product'); 
 

 
$i = 0; while ($z->name === 'Product') 
 
{ $i++; 
 
$node = simplexml_import_dom($doc->importNode($z->expand(), true)); 
 

 
...

Answer 1

我想这应该这样做。

$simpleXml = new SimpleXMLElement(file_get_contents($datei)); 
foreach ($simpleXml->Products->Product as $product) { 
    $name = $product->xpath('Name[@xml:lang="en"]')[0]; 
    echo $name . "\n"; 
    foreach($product->Image as $img) { 
     echo $img->Url . "\n"; 
    } 
} 

Answer 2

xpath使用许多resurses。您可以扫描它，并获取所需的节点。在代码中，您将看到如何获取具有前缀的节点和属性的名称和值。

$simpleXml = new SimpleXMLElement(file_get_contents($datei))); 
foreach ($simpleXml->Products->Product as $products)  // list of nodes with same name 
    foreach($products as $product) {      // every node 
    if ($product->getName() === 'Image') {    // for image take child 
     echo $product->Url->getName() . " = " . $product->Url ."\n"; 
     $attrs = $product->attributes();     // Attribute without prefix 
     if(isset($attrs['num'])) echo " num = " . $attrs['num'] . "\n"; 
    } 
    else echo $product->getName() . " = " . $product ."\n"; 

    $attrs = $product->attributes('xml', true);   // if 2nd true, 1st is prefix 
    if(isset($attrs['lang'])) echo " lang = " . $attrs['lang'] . "\n"; 
} 

结果

Id = 123 
Name = name english product 
    lang = en 
Description = desc xyz 
    lang = en 
Name = name german 
    lang = de 
Description = desc germa 
    lang = de 
Url = pic.jpg 
    num = 1 
Url = pic2.jpg 
    num = 2
