将xml转换为数组，无法处理节点内的节点

发布于 2024-11-16 13:07:59 字数 654 浏览 3 评论 0原文

我想将 xml 脚本转换为 PHP 中的关联数组。 XML 脚本是：

<ages>
    <Peter>
        <Peterchild>4</Peterchild>
        <Peterchild>6</Peterchild>
    </Peter>
    <Quagmire>30</Quagmire>
    <Joe>34</Joe>
</ages>

我编写的用于将其转换为数组的代码是，

${$xml->getName()} = array();
foreach($xml->children() as $child){
    $ages[$child->getName()] = (string)$child;
}

它给出的输出为

Array
(
    [Peter] => 



    [Quagmire] => 30
    [Joe] => 34
)

问题是我无法找出递归遍历孩子的孩子的条件（在本例中是 Peter 的孩子）。如何更改此代码以也考虑这些节点？

I want to convert a xml script into a associative array in PHP. The XML script is :

<ages>
    <Peter>
        <Peterchild>4</Peterchild>
        <Peterchild>6</Peterchild>
    </Peter>
    <Quagmire>30</Quagmire>
    <Joe>34</Joe>
</ages>

and the code i wrote for converting it to an array is

${$xml->getName()} = array();
foreach($xml->children() as $child){
    $ages[$child->getName()] = (string)$child;
}

which gives the output as

Array
(
    [Peter] => 



    [Quagmire] => 30
    [Joe] => 34
)

The problem is that I am unable to figure out a condition to recursively traverse through the children of children (children of Peter in this example). How to I change this code to consider those nodes as well?

您需要创建一个解析一个级别的函数，然后让该函数在找到当前级别内的节点时调用自身。它非常复杂并且可能会变得混乱。出于好奇，当您可以使用 SimpleXML 对象以对象格式访问所需的所有信息时，为什么要这样做呢？

${$xml->getName()} = array();
    foreach($xml->children() as $child) 
    {
      if (count($child->children() > 0) 
      {
         foreach ($child->children as $childnode)
         {
           $ages[$childnode->getName()] = (string)$childnode;
         }
      }
      else {
          $ages[$child->getName()] = (string)$child;
      }
   }

这仅在深度为 1 级时才有效，如果要达到更多级别，您应该编写一个函数，该函数将逐级循环。

${$xml->getName()} = array();
    foreach($xml->children() as $child) 
    {
      if (count($child->children() > 0) 
      {
         foreach ($child->children as $childnode)
         {
           $ages[$childnode->getName()] = (string)$childnode;
         }
      }
      else {
          $ages[$child->getName()] = (string)$child;
      }
   }

This will only work if it is 1 level deep, if it is going to be more levels you should write a function, that will cycle through it level by level.
