使用PHP(DOM)迭代未知的XML结构

Question

我想编写一个函数,将(理论上)未知的XML数据结构解析为等效的PHP数组.

这是我的示例XML:

<?xml version="1.0" encoding="UTF-8"?>
<content>

<title>Sample Text</title>

<introduction>
    <paragraph>This is some rudimentary text</paragraph>
</introduction>
<description>
    <paragraph>Here is some more text</paragraph>
    <paragraph>Even MORE text</paragraph>
    <sub_section>
        <sub_para>This is a smaller, sub paragraph</sub_para>
        <sub_para>This is another smaller, sub paragraph</sub_para>
    </sub_section>
</description>
</content>

我从devarticles修改了这个DOM迭代函数:

$data = 'path/to/xmldoc.xml';
$xmlDoc = new DOMDocument(); #create a DOM element
$xmlDoc->load( $data ); #load data into the element
$xmlRoot = $xmlDoc->firstChild; #establish root

function xml2array($node)
    {
    if ($node->hasChildNodes())
    {
$subNodes = $node->childNodes;
    foreach ($subNodes as $subNode)
        {
        #filter node types
        if (($subNode->nodeType != 3) || (($subNode->nodeType == 3)))   
            {
            $arraydata[$subNode->nodeName]=$subNode->nodeValue;
            }
         xml2array($subNode);
         }
      }
      return $arraydata;
   }
//The getNodesInfo function call

 $xmlarray = xml2array($xmlRoot);


// print the output - with a little bit of formatting for ease of use...
foreach($xmlarray as $xkey)
     {
     echo"$xkey<br/><br/>";
     }

现在,由于我将元素传递给数组的方式,我正在覆盖共享节点名称的任何元素(因为我理想地希望为这些键提供与其原始节点相同的名称).我的递归并不好......但是,即使我清空括号 - 第二层节点仍然作为第一层的值出现(参见描述节点的文本).

任何人都有任何想法,我怎么能更好地构建这个？
