Question

我有这个XML文件：

<images>
<photo image="images/101.jpg" colorboxImage="images/101.jpg" colorboxInfo="Item 01" colorboxClass="image" url = "http://www.flashxml.net" target="_blank">
<![CDATA[<head>Hello</head><body>Welcome to the new Circular Gallery</body>]]></photo>

<photo image="images/102.jpg" colorboxImage="images/102.jpg" colorboxInfo="Item 02" colorboxClass="image" url = "http://www.flashxml.net" target="_blank">
<![CDATA[<head>Download the new Circular Gallery</head><body>for FREE</body>]]></photo>

<photo image="images/103.jpg" colorboxImage="images/103.jpg" colorboxInfo="Item 03" colorboxClass="image" url = "http://www.flashxml.net" target="_blank">
<![CDATA[<head>Insert it in your website</head><body>without any special skills or software</body>]]></photo>

<photo image="images/104.jpg" colorboxImage="images/104.jpg" colorboxInfo="Item 04" colorboxClass="image" url = "http://www.flashxml.net" target="_blank">
<![CDATA[<head>Put your own images in the "images" folder</head><body>and update the images.xml file accordingly</body>]]></photo>

<photo image="images/105.jpg" colorboxImage="images/105.jpg" colorboxInfo="Item 05" colorboxClass="image" url = "http://www.flashxml.net" target="_blank">
<![CDATA[<head>You can put <a href="http://www.flashxml.net" target="_blank">links</a> in this HTML/CSS formatted text</head><body>and you can also put links behind the images</body>]]></photo></images>

和这个PHP代码：

$xml = simplexml_load_file("images.xml");

foreach ($xml->children() as $child)
  {
  echo "Child node: " . $child . "<br />" . $child["image"] . "<br />";

  }

我得到的结果如下：

Child node: HelloWelcome to the new Circular Gallery
images/101.jpg
Child node: Download the new Circular Galleryfor FREE
images/102.jpg
Child node: Insert it in your websitewithout any special skills or software
images/103.jpg

我想分开这一部分的文字：

<![CDATA[<head>You can put <a href="http://www.flashxml.net" target="_blank">links</a> in this HTML/CSS formatted text</head><body>and you can also put links behind the images</body>]]>

我想阅读头部和身体部分的文字，但是这段代码将它们合并为一个文本，我不知道如何获取每一个并做我需要做的事情

看起来您必须再次解析节点内容（使用simplexml_load_string）。但我发现SimpleXMLElement中没有函数来检索节点的文本内容，只检索子元素。奇怪。

但看起来转换为节点的字符串会返回此节点的内容，因此您可以尝试这样做：

$xml = simplexml_load_file("images.xml");

foreach ($xml->children() as $child)
{
   echo "Child node: " . $child . "<br />" . $child["image"] . "<br />";
   $content = simplexml_load_string("<dummy>". $child . "</dummy>");
   echo "child head: " . $content->head . "<br/>";
   echo "child body: " . $content->body . "<br/>";
}

如何处理这些XML数据？
