I had a feature to the XmlConstruct class by Alexandre Aprica. Now you can use nested array to generate nested xml elements.

<?php
class XmlConstruct extends XMLWriter
{

    /**
     * Constructor.
     * @param string $prm_rootElementName A root element's name of a current xml document
     * @param string $prm_xsltFilePath Path of a XSLT file.
     * @access public
     * @param null
     */
    public function __construct($prm_rootElementName, $prm_xsltFilePath=''){
        $this->openMemory();
        $this->setIndent(true);
        $this->setIndentString(' ');
        $this->startDocument('1.0', 'UTF-8');

        if($prm_xsltFilePath){
            $this->writePi('xml-stylesheet', 'type="text/xsl" href="'.$prm_xsltFilePath.'"');
        }

        $this->startElement($prm_rootElementName);
    }

    /**
     * Set an element with a text to a current xml document.
     * @access public
     * @param string $prm_elementName An element's name
     * @param string $prm_ElementText An element's text
     * @return null
     */
    public function setElement($prm_elementName, $prm_ElementText){
        $this->startElement($prm_elementName);
        $this->text($prm_ElementText);
        $this->endElement();
    }

    /**
     * Construct elements and texts from an array.
     * The array should contain an attribute's name in index part
     * and a attribute's text in value part.
     * @access public
     * @param array $prm_array Contains attributes and texts
     * @return null
     */
    public function fromArray($prm_array){
      if(is_array($prm_array)){
        foreach ($prm_array as $index => $element){
          if(is_array($element)){
            $this->startElement($index);
            $this->fromArray($element);
            $this->endElement();
          }
          else
            $this->setElement($index, $element);
         
        }
      }
    }

    /**
     * Return the content of a current xml document.
     * @access public
     * @param null
     * @return string Xml document
     */
    public function getDocument(){
        $this->endElement();
        $this->endDocument();
        return $this->outputMemory();
    }

    /**
     * Output the content of a current xml document.
     * @access public
     * @param null
     */
    public function output(){
        header('Content-type: text/xml');
        echo $this->getDocument();
    }
  

}

Example:

$contents = array(
  'page_title' => 'Generate a XHTML page from XML+XSLT files',
  'welcome_msg' => 'Simple XHTML document from XML+XSLT files!',
  'prova' => array(
    "gino" => array(
      "innergino" => "gino inner value"
    ),
    "filo" => "filodata"
  ),
);

$XmlConstruct = new XmlConstruct('root');
$XmlConstruct->fromArray($contents);
$XmlConstruct->output();
?>

If you want your XML-output to be seen as XML by the browser, you need to modify your header. The XmlWriter does not do this for you! Therefore, the first line of your script should be:

<?php header("Content-type: text/xml"); ?>

How to generate a simple XML document for a XSL-Transformation purpose.

We have 3 files:
- 'index.php' : output a XML document
- 'XmlConstruct.class.php' : allow to construct a XML document with 'xmlwriter'
- 'index.xsl' : contains a XSLT document

Contents of the file 'index.php' :

<?php
$contents = array('page_title' => 'Generate a XHTML page from XML+XSLT files',
                    'welcome_msg' => 'Simple XHTML document from XML+XSLT files!');

require('XmlConstruct.class.php');
$XmlConstruct = new XmlConstruct('rootElement', 'index.xsl');
$XmlConstruct->fromArray($contents);
$XmlConstruct->output();
?>

Contents of the file  'XmlConstruct.class.php' :

<?php

/**
 * Construct a simple XML document.
 * This class inherits from the (PHP) class 'xmlwriter'.
 * You will need at least PHP 5.1.2

Using XMLWriter to create a WAP page:

<?php
$memory = xmlwriter_open_memory();
xmlwriter_start_document($memory,'1.0','UTF-8');
xmlwriter_start_dtd($memory,'html','-//WAPFORUM//DTD XHTML Mobile 1.0//EN', 'http://www.wapforum.org/DTD/xhtml-mobile10.dtd');
xmlwriter_end_dtd($memory);
xmlwriter_start_element ($memory,'html'); // <html>
xmlwriter_write_attribute( $memory, 'xmlns', 'http://www.wapforum.org/DTD/xhtml-mobile10.dtd');
xmlwriter_write_attribute( $memory, 'xm:lang', 'en');

xmlwriter_start_element($memory,'head'); // <head>

xmlwriter_write_element ($memory,'title', 'Test WAP Document');

xmlwriter_end_element($memory); // </head>
xmlwriter_start_element($memory,'body'); // <body>
xmlwriter_start_element($memory,'ol'); // <ol>

xmlwriter_write_element ($memory,'li', 'One Item');
xmlwriter_write_element ($memory,'li', 'Another Item');
xmlwriter_write_element ($memory,'li', 'Another Item');

xmlwriter_end_element($memory); // </ol>
xmlwriter_end_element($memory); // </body>
xmlwriter_end_element($memory); // </html>

xmlwriter_end_dtd($memory);
$xml = xmlwriter_output_memory($memory,true);
?>

Output:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" "http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
<html xmlns="http://www.wapforum.org/DTD/xhtml-mobile10.dtd" xm:lang="en">
<head>
<title>Test WAP Document</title>
</head>
<body>
<ol>
<li>One Item</li>
<li>Another Item</li>
<li>Another Item</li>
</ol>
</body>
</html>
