在php中组合XML文件

合并多个文件可以执行以下操作。。。

function mergeFile ( DOMDocument $target, $fileName )    {
    $source = new DOMDocument();
    $source->load($fileName);

    foreach ( $source->getElementsByTagName("row") as $row )   {
        $import = $target->importNode($row, true);
        $target->documentElement->appendChild($import);
    }
}

$target = new DOMDocument();
$target->loadXML('<?xml version="1.0" encoding="utf-8"?><sales></sales>');
mergeFile($target, "NewFile.xml");
mergeFile($target, "NewFile1.xml");
mergeFile($target, "NewFile2.xml");

$target->save("out2.xml");

这允许您继续将所有文件添加到一起,然后在最后保存它们。

根据中的答案: Merge XML files in PHP

$doc1 = new DOMDocument();
$doc1->load('1.xml');

$doc2 = new DOMDocument();
$doc2->load('2.xml');

// get 'res' element of document 1
$res1 = $doc1->getElementsByTagName('items')->item(0); //edited res - items

// iterate over 'item' elements of document 2
$items2 = $doc2->getElementsByTagName('item');
for ($i = 0; $i < $items2->length; $i ++) {
    $item2 = $items2->item($i);

    // import/copy item from document 2 to document 1
    $item1 = $doc1->importNode($item2, true);

    // append imported item to document 1 'res' element
    $res1->appendChild($item1);

}
