Valid XML creation with PHP

[mavera2]

 

With the following code i can create an xml file.

<?php
$myXML = new SimpleXMLElement("<myroot></myroot>");
$title= $myXML->addChild('title');
$title->addAttribute('number','12');
$titleName= $title->addChild('titleName', 'title1');
$titleLink= $title->addChild('titleLink', 'link1');
Header('Content-type: text/xml');
echo $myXML->asXML();
?>

 

But when i check the validity of xml file

http://www.validome.org/xml/validate/

This error occurs:

Can not find declaration of element 'myroot'.

 

I suppose that the problem is missing of

!DOCTYPE and

!ELEMENT lines.

 

How can i create valid XML documents with PHP automatically??

Is it possible to make it without writing doctype and element types

for the whole element types of xml by hand

$title, $titleName and $titleLink

 

Thank you

It's the validator that's the problem, your code produces a valid output.

<?xml version="1.0"?>
<myroot><title number="12"><titleName>title1</titleName><titleLink>link1</titleLink></title></myroot>

Try http://validator.w3.org/.
