SimpleXML 追加多个文件
SimpleXML append multiple files
我正在尝试合并多个 XML 文件，如果可能的话使用 SimpleXML。我只是想将文件 2 中的产品、children 和 child 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，等等。 （虽然我猜这在技术上是合并商家元素？）这些文件包含相同的模式并且看起来都类似于下面的示例，唯一会改变的是实际文本。这只是两个不同产品的 XML，我在产品之间添加了一个大的 space，以便更容易看到它的结束位置。

Our new cotton socks are designed by Sunspel and crafted in an Italian factory steeped in years of experience, skill and heritage. They are made from the highest quality, extra-long staple Egyptian cotton yarn which, prior to knitting is combed, twisted and mercerised to enhance the comfort, shine and absorption of the fabric as well as its resistance to pilling and shrinking.

通过一些 foreach 语句，我可以附加所有产品 children 和属性，但这实际上并没有给我 child 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( $fh );
当我尝试从那里添加时，一切都变得一团糟，没有任何内容是正确的 place/order。我也想把它放到一个函数中，因为我会经常这样做。非常感谢任何帮助，因为我已经为此苦苦挣扎了几天，并且已经浏览了几十个 Whosebug 和 php.net 线程。
让我感到困惑的一件事是每个文件开头的 <merchandiser> 和 <header> 标记。一旦商品标签结束，它就是文档的结尾，所以我只需要获取文件 2 的商品标签内的内容，并将其附加到文件 1 的商品标签内。header 标签让我感到困惑，因为我'我不确定它是否妨碍了。
初步说明，您的 XML 样本格式不正确。它也与您的代码不一致（即没有 ->merchandiser->header->product ）。
所以，在这个例子中，我将使用不同的样本，比如这个 (file1.xml):
<root>
<product>
<name>Product 1</name>
</product>
<product>
<name>Product 2</name>
</product>
</root>
还有这个 (file2.xml):
<root>
<product>
<name>Product 3</name>
</product>
<product>
<name>Product 4</name>
</product>
</root>
您不想使用 DOMDocument->importNode()，因为“它一直抛出很多错误”。
您可以将 DOMDocument 与 SimpleXML 和 dom_import_simplexml() 函数结合使用。
首先，准备目的地XML：使用SimpleXML加载文件，使用dom_import_simplexml()创建DOMDocument并将$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，加载第二个文件 SimpleXML:
$src = simplexml_load_file( 'file2.xml' );
通过 foreach() 循环，将每个 <product> 元素从 SimpleXML 导入到 DOMDocument 并将其附加为 $parent 节点的子节点：
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>
