我有以下 xml 文件：<products><info><productName>Chocolate Cake</productName> <productDescription>uieovbeveb</productDescription><quantity>1</quantity><stock>22</stock><price>2.99,12.99</price><size>200 ml</size><type>India,colombia</type></info><info><productName>watermelon</productName><productDescription>fr</productDescription><quantity>rf</quantity><stock>34</stock><price>4</price><size>4</size><type>5</type></info></products>我想訪問其中一個產(chǎn)品的 ProductDescription 標(biāo)簽之一并更改其值，但它不起作用。這是我到目前為止所嘗試的：if (isset($_POST['editProduct'])) {$xml = new DomDocument("1.0", "UTF-8");$xml->load('./data/productDB.xml');$productName = $_POST['productName'];$productDescription = $_POST['productDescription'];$quantity = $_POST['quantity'];$stock = $_POST['stock'];$price = $_POST['price'];$size = $_POST['size'];$type = $_POST['type'];$sizetoString = implode(",", $size);$typetoString = implode(",", $type);$pricetoString = implode(",", $price);$products = $xml->getElementsByTagName('info');foreach($products as $product) { $nameOfProduct = $product->getElementsByTagName('productName')->item(0)->nodeValue; if($nameOfProduct == $productName) { $product->getElementsByTagName('productDescription')->item(0)->nodeValue=""; $product->getElementByTagName('productDescription')->item(0)->appendChild($product->createTextNode($productDescription)); }}$xml->save("./data/productDB.xml");

試試這個例子：
// load the document
$products = simplexml_load_file('test.xml');
// loop through each product and change description
foreach($products as $product) {
$product->productDescription = 'new description';
}
// save the new xml
$products->asXML('test.xml');
