PHP DOM saveXML() prblm !!

[ivobenedito]

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 :

<?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);
?>

Does anyone know what may be the problm ?? It just doesn't work with or without argument's in saveXML method and doesn't output any compilation error. I just get a blank browser screen ;( !!

The first thing to do is run phpinfo() and see if DOM is enabled in your server.
If it is enabled, "view source" after running the script in your browser. You'll probably see the results your looking for. In my opinion, the examples for the DOM function aren't very clear. If you want to see the results in your browser without having to view source then call header('Content-type: text/xml'); at the beginning of your xml. You'll have to delete the echo'd text lines or else it won't work.

<?php
header('Content-type: text/xml');
$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 $doc->saveXML();
?>

Tks for the help samudasu 😉 !!

BTW, another way for printing the xml for test proposes in the page is using something like

 echo '<pre>' . htmlentities($doc->saveXML()) . '</pre>';
