The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.

Try this

<?php
$string = <<<XML
<a>
<b>
<c>text</c>
<c>stuff</c>
</b>
<d>
<c>code</c>
</d>
</a>
XML;
$xml = new SimpleXMLElement($string);
 $xml->asXML()."<br>";


    //echo "<c>".(string)$child."</c>";
    foreach( $xml->children() AS $child )
{
    //run any query you want on the children.. they are also nodes.
   $name1 = $child;
   //echo "<pre><c></pre>".$name1."<pre><c></pre><br>";
   foreach( $name1->children() AS $child1 )
{
     $name2 = $child1->getName();
     $child2=$child1;
    // echo $name2."--".$child2;
        echo "&lt;".$name2."&gt;".$child2."&lt;&frasl;".$name2."&gt;"."<br>";

}

}

?>

thank you.. but not like that.. if b node has value like <b id="tp01"> means it returns b child nodes..

echo nl2br(htmlentities(getChildXML($string, 'b', 'tp001')));
why linebreak is not working here.
