SimpleXML附加多个文件

标签： php xml simplexml

我正在尝试组合多个XML文件，如果可能的话使用SimpleXML。我只是想将文件2中的产品，子项和子数据附加到文件1中。我不是要合并元素，只是将文件2附加到文件1的底部，依此类推。 （虽然我猜这在技术上是合并商品元素？）文件包含相同的模式，并且看起来都类似于下面的示例，只有改变的是实际文本。这只是两种不同产品的XML，我在产品之间添加了一个大空间，以便更容易看到它的结束位置。

通过一些foreach语句，我能够附加所有产品子项和属性，但这实际上并没有给我孩子数据。 

    $file1 = '35928_3210820_mp.xml';
$file2 = '39153_3210820_mp.xml';
$fileout = 'ukmerge.xml';
$xml1 = simplexml_load_file( $file1 );
$xml2 = simplexml_load_file( $file2 );  // loop through the product and add them and their attributes to xml1
$product = $xml2->product;
$prod = $xml2->merchandiser->header->product;
$category = $product->category;
$url = $product->URL;
$description = $product->description;
foreach( $xml2->children() as $child ) {
    $new = $xml1->addChild( $child->getName() , htmlspecialchars($child) );
    foreach( $child->attributes() as $key => $value ) {
        $new->addAttribute( $key, $value );

        }
    }   $fh = fopen( $fileout, 'w') or die ( "can't open file $fileout" );
fwrite( $fh, $xml1->asXML() );
fclose( $fh );

当我尝试从那里添加时，一切都搞砸了，没有任何东西在正确的位置/顺序。我也想把它放到一个函数中，因为我将经常这样做。任何帮助都非常感激，因为我已经在这几天苦苦挣扎，并且已经浏览了几十个stackoverflow和php.net线程。

令我困惑的一件事是每个文件都以<merchandiser>和<header>标记开头。一旦商品标签结束，它就是文件的末尾，所以我只需要拿出文件2的商品标签内的内容并将其附加到文件1的商品标签内。标头标签只会让我感到困惑，因为我不确定是否它会妨碍你。

1 个答案:

答案 0 :(得分：0)

初步说明，您的XML示例格式不正确。它也与你的代码不一致（即没有->merchandiser->header->product）。

所以，在这个例子中，我将使用不同的样本，例如这个样本（ file1.xml ）：

<root>
    <product>
        <name>Product 1</name>
    </product>
    <product>
        <name>Product 2</name>
    </product>
</root>

和这个（ file2.xml ）：

<root>
    <product>
        <name>Product 3</name>
    </product>
    <product>
        <name>Product 4</name>
    </product>
</root>

您不想使用DOMDocument->importNode()因为“它会导致很多错误”。

您可以将DOMDocument与SimpleXML和dom_import_simplexml()功能结合使用。

首先，准备目标XML：使用SimpleXML加载文件，使用DOMDocument创建dom_import_simplexml()并将$parent变量设置为<root>元素： 

$dst = simplexml_load_file( 'file1.xml' );
$dst = dom_import_simplexml( $dst )->ownerDocument;
$parent = $dst->getElementsByTagName( 'root' )->item(0);

然后，使用SimpleXML加载第二个文件：

$src = simplexml_load_file( 'file2.xml' );

通过foreach()循环，将每个<product>元素从SimpleXML导入DOMDocument，并将其作为$parent节点的子项添加：

foreach( $src->product as $product )
{
    $node = dom_import_simplexml( $product );
    $node = $dst->importNode( $node, 1 );
    $parent->appendChild( $node );
}

现在，您的合并XML已准备就绪。您可以使用$dst->saveXML()打印它。

我无法生成正确缩进的XML。顺便说一句，你可以重新加载它：

$final = new DOMDocument();
$final->loadXML( $dst->saveXML(), LIBXML_NOBLANKS );
$final->formatOutput = True;
echo $final->saveXML();

最终输出：

<?xml version="1.0"?>
<root>
  <product>
    <name>Product 1</name>
  </product>
  <product>
    <name>Product 2</name>
  </product>
  <product>
    <name>Product 3</name>
  </product>
  <product>
    <name>Product 4</name>
  </product>
</root>
