在PHP节点值和元素中创建的Xml

问题描述：

I do not understand these node value things at all i am trying to replicate an xml design in php but
having quite a bit of trouble the file i am trying to reproduce through php is.

   <items>
        <item>
              <id></id>
              <name></name>
              <price></price>
              <quantity></quantity>
              <description></description>
              <qonhold></qonhold>
              <qsold></qsold>
        </item>
     </items>

And the PHP file to recreate this is almost all done

  $dom = new DOMDocument("1.0");

  // create root element
  $root = $dom->createElement("Items");
  $dom->appendChild($root);
  $dom->formatOutput=true;

  // create child element
  $item = $dom->createElement("item");
  $dom->appendChild($item);

  // create text node
  $id = $dom->createElement("id");
  $root->appendChild($id);

  $name = $dom->createElement("name");
  $root->appendChild($name);


  $price = $dom->createElement("price");
  $root->appendChild($price);

  $quantity = $dom->createElement("quantity");
  $root->appendChild($quantity);

  $description = $dom->createElement("description");
  $root->appendChild($description);


  $qonhold = $dom->createElement("qonhold");
  $root->appendChild($qonhold);


  $qsold = $dom->createElement("qsold");
  $root->appendChild($qsold);

The problem i am having is its saving it all under "items" being the root.. but i can not get everything id, name, price, quantity, description, qonhold, qsold to save under just "item" which is saved under "items

我根本不理解这些节点值的东西我试图在php中复制xml设计但是
我试图通过PHP重现的文件有相当多的麻烦。
p>

 ＆lt; items＆gt; 
＆lt; item＆gt; 
＆lt; id＆gt;＆lt; / id＆gt; 
＆lt; name＆gt;＆lt; / name＆gt; \  n＆lt; price＆gt;＆lt; / price＆gt; 
＆lt; quantity＆gt;＆lt; / quantity＆gt; 
＆lt; description＆gt;＆lt; / description＆gt; 
＆lt; qonhold＆gt;＆lt; / qonhold＆gt; 
＆lt; qsold＆gt;＆lt;  ; / qsold＆gt; 
＆lt; / item＆gt; 
＆lt; / items＆gt; 
  code>  pre> 
 
 重新创建此文件的PHP文件几乎全部完成 p>  
 
 
  $ dom = new DOMDocument（“1.0”）; 
 
 //创建根元素
 $ root = $ dom-＆gt; createElement（“Items”）; 
 $  dom-＆gt; appendChild（$ root）; 
 $ dom-＆gt; formatOutput = true; 
 
 //创建子元素
 $ item = $ dom-＆gt; createElement（“item”）; 
 $  dom-＆gt; appendChild（$ item）; 
 
 //创建文本节点
 $ id = $ dom-＆gt; createElement（“id”）; 
 $ root-＆gt; appendChild（$ id）; \  n 
 $ name = $ dom-＆gt; createElement（“name”）; 
 $ root-＆gt; appendChild（$ name）; 
 
 
 $ price = $ dom-＆gt; createElement（“p  rice“）; 
 $ root-＆gt; appendChild（$ price）; 
 
 $ quantity = $ dom-＆gt; createElement（”quantity“）; 
 $ root-＆gt; appendChild（$ quantity）; \  n 
 $ description = $ dom-＆gt; createElement（“description”）; 
 $ root-＆gt; appendChild（$ description）; 
 
 
 $ qonhold = $ dom-＆gt; createElement（“qonhold”  ）; 
 $ root-＆gt; appendChild（$ qonhold）; 
 
 
 $ qsold = $ dom-＆gt; createElement（“qsold”）; 
 $ root-＆gt; appendChild（$ qsold）; \  n  code>  pre> 
 
 我遇到的问题是它在“items” i>作为根目录下保存了所有内容..但我无法得到所有内容 id，name，price，quantity，description，qonhold，qsold  i>保存在“item” i>下，保存在“items  i>  p> \下 n  div>

答

You should use ->appendChild() on the item node created, not the root which is <items>:

// create child element
$item = $dom->createElement("item");
$dom->appendChild($item);

// create text node
$id = $dom->createElement("id");
$item->appendChild($id); // item->appendChild not $root->appendChild

Should look like this:

$dom = new DOMDocument("1.0");

// create root element
$root = $dom->createElement("Items");
$dom->appendChild($root);
$dom->formatOutput=true;

// create child element
$item = $dom->createElement("item");
$root->appendChild($item); // append to `<Items>`

// create text node
$id = $dom->createElement("id");
$item->appendChild($id); // append to `<item>`

$name = $dom->createElement("name");
$item->appendChild($name); // append to `<item>`


$price = $dom->createElement("price");
$item->appendChild($price); // append to `<item>`

$quantity = $dom->createElement("quantity");
$item->appendChild($quantity); // append to `<item>`

$description = $dom->createElement("description");
$item->appendChild($description); // append to `<item>`


$qonhold = $dom->createElement("qonhold");
$item->appendChild($qonhold); // append to `<item>`


$qsold = $dom->createElement("qsold");
$item->appendChild($qsold); // append to `<item>`
