PHP DOM and saveXML() Method !!

Hi,

I’m creating a new XML Document in php using PHP DOM and when i use the method saveXML() i just get a blank string instead of a string with the content of the xmlDoc that i created. Here is the code :

[CODE]<?php
$doc = new DOMDocument(‘1.0’);
$doc->formatOutput = true;

$root = $doc->createElement(‘book’);
$root = $doc->appendChild($root);

$title = $doc->createElement(‘title’);
$title = $root->appendChild($title);

$text = $doc->createTextNode(‘This is the title’);
$text = $title->appendChild($text);

echo “Retrieving all the document:n”;
echo $doc->saveXML() . “n”;

echo “Retrieving only the title part:n”;
echo $doc->saveXML($title);
?>[/CODE]

Does anyone knows what is the problm ??

Also in #PHP _↴
