loadXML throws "Only one top level element is allowed in an XML document"

Hi all,

I have just started experimenting with php & xml.

Followed the samples came with the DOM API section on this site. I was able to load the book.xml from the file system with the code like this.

Code:

---

<?php
$doc = DOMDocument::load('book.xml');
echo $doc->saveXML();

$doc = new DOMDocument();
$doc->load('book.xml');
echo $doc->saveXML();
?>

---

However, when I want to load from a string, like below.

Code:

---

<?php
$doc = DOMDocument::loadXML('<root><node/></root>');
echo $doc->saveXML();

$doc = new DOMDocument();
$doc->loadXML('<root><node/></root>');
echo $doc->saveXML();
?>

---

I got this error.
