使用xpath和php获取子元素[关闭]

I have this sample xml file:-

<products>
   <product_id value="1">
       <tab_id value="251">
            <dist_region value="5" />
            <dist_region value="10066" />
            <dist_region value="10069" />
       </tab_id>
   </product_id>
</products>

I am trying to get tab_id child element using XPathand I want result in set of child elements.

My expected output is as follows:-

dist_region,dist_region,dist_region

MY XPATH:-

$tab = $product->xpath('//tab_id/*');

Can anyone suggest what is the XPath to get child elements? Thanks.

    Your XPath should be based on specific condition like value (if it is <tab_id id='256'> then more readable)

    $result = $product->query('//tab_id[@value=' . $id . ']/*');
    

    and then loop through it like below

    if($result->length){
        foreach ($result as $item):
            echo "Value: ".$item['value'];
        echo "<hr>";
    endforeach;
    }
