Question

我有一个定义表单字段的xml文件。对于带有optgroups的列表，我的xml将包含类似

的内容

<field
    name="expertise"
    type="multilist"
    label="Area of Expertise"
>
    <option value="Disaster Management">Disaster Management </option>
    <option value="Energy Security">Energy Security </option>
    <optgroup label="Environment">
        <option value="Climate">Climate </option>
        <option value="Resource Security">Resource Security </option>
    </optgroup>
</field>

我试图循环遍历

等节点

foreach ($feed->fieldset[1]->field[$j]->children() as $c):
    foreach($c->attributes() as $key => $value):
        echo '<'.$c->getName().' '.$key.'="'.$value.'">'.$c.'</'.$c->getName().'><br>';
    endforeach;
endforeach;

我知道，对于等于标签的价值可能没有意义，但我稍后会担心。

目前，我正试图弄清楚如何遍历optgroup中的选项和选项。上面的循环没有显示optgroup的选项（如预期的那样）。似乎我可能不得不做一些递归，但是想知道是否有更好的方法可以推荐，比如现有的php xml函数可以处理我想要做的事情（到目前为止我还没有找到任何东西）。

谢谢！

Answer 2

我最终让它像这样工作。主要的是我需要能够标记为之前选择的选定选项。

If pptShape.Type = msoLinkedOLEObject Or 
   pptShape.Type = msoLinkedPicture Or pptShape.Type = msoChart Then

使用PHP解析XML格式的选项和optgroup
