我愿做一个数，发现有在XML文档中 <Other>标签。

我已经能够算的<OtherDetails>标签数（答案是）如下：当我尝试下去，数到返回0 <Other>标签水平

if (!empty($Record->PersonDetails->OtherRelatedDetails->OtherDetails)) { 

    foreach ($Record->PersonDetails->OtherRelatedDetails->OtherDetails as $NumberOfOtherDetails) { 

     $theNumberOfOthers = $NumberOfOtherDetails->count(); //returns 2 
    } 
}

有什么办法可以克服这个问题吗？

显示，你就装XML内容 – RomanPerekhrest

@BernardV希望我的文章会帮助你的代码... –

@RomanPerekhrest我加载如下：'$ theXML = new SimpleXMLElement（$ stringBody）;' – BernardV

试试这个最简单的。

Try this code snippet here

<?php 

ini_set('display_errors', 1); 
libxml_use_internal_errors(true); 
$domObj= new DOMDocument(); 
$domObj->loadXML('<Record> 
<PersonDetails> 
    <StuffA>050656770</StuffA> 
    <StuffB>Stuff B Content</StuffB> 
    <StuffC>Stuff C Content</StuffC>    
</PersonDetails> 
<PersonDetails> 
    <StuffA>050656770</StuffA> 
    <StuffB>Stuff B Content</StuffB> 
    <StuffC>Stuff C Content</StuffC> 
</PersonDetails> 
<PersonDetails> 
    <StuffA>050656770</StuffA> 
    <StuffB>Stuff B Content</StuffB>

这是行不通的，非常感谢Sahil Gulati **但是**现在得到一个计数我必须使用DOMDocument来导入我的XML，你相信有什么办法可以这样做：SimpleXMLElement？谢谢！ – BernardV

谢谢@Sahil Gulati，我现在正在测试这个！ – BernardV

我会肯定的，谢谢你的协助！（已经投票了！） – BernardV
