CLXXVIII. XMLWriter Functions
This is the XMLWriter extension. It wraps the libxml xmlWriter API.
This extension represents a writer that provides a non-cached,
forward-only means of generating streams or files containing XML data.
This extension can be used in an object oriented style or a procedural
one. Every method documented describes the alternative procedural call.

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:
header("Content-type: text/xml");

Hi,
There already is a class xmlWriter, although it is not documented. This is a rewrite of the example from [http://cz2.php.net/manual/en/ref.xmlwriter.php#64484 Carlos Averett] and works well on my php 5.1.6
<?php
$xw = new xmlWriter();
$xw->openMemory();
$xw->startDocument('1.0','UTF-8');
$xw->startDtd('html','-//WAPFORUM//DTD XHTML Mobile 1.0//EN', 'http://www.wapforum.org/DTD/xhtml-mobile10.dtd');
$xw->endDtd();
$xw->startElement ('html'); $xw->writeAttribute( 'xmlns', 'http://www.wapforum.org/DTD/xhtml-mobile10.dtd');
$xw->writeAttribute( 'xm:lang', 'en');
$xw->startElement('head'); $xw->writeElement ('title', 'Test WAP Document');
$xw->endElement(); $xw->startElement('body'); $xw->startElement('ol'); $xw->writeElement ('li', 'One Item & <sss <ss />></ss>');
$xw->writeElement ('li', 'Another Item');
$xw->writeElement ('li', 'Another Item');
$xw->endElement(); $xw->endElement(); $xw->endElement(); $xw->endDtd();
print $xw->outputMemory(true);
?>

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);
$XmlConstruct->output();
?>
Contents of the file 'XmlConstruct.class.php' :
<?php
class XmlConstruct extends XMLWriter
{
public function __construct($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);
}
public function setElement($prm_elementName, $prm_ElementText){
$this->startElement($prm_elementName);
$this->text($prm_ElementText);
$this->endElement();
}
public function fromArray($prm_array){
if(is_array($prm_array)){
foreach ($prm_array as $index => $text){
$this->setElement($index, $text);
}
}
}
public function getDocument(){
$this->endElement();
$this->endDocument();
return $this->outputMemory();
}
public function output(){
header('Content-type: text/xml');
echo $this->getDocument();
}
}
?>
Contents of the file 'index.xsl' :
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://www.w3.org/TR/xhtml1/strict">
<xsl:output
method="html"
encoding="utf-8"
/>
<xsl:template match="rootElement">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title><xsl:value-of select="page_title" /></title>
</head>
<body>
<xsl:value-of select="welcome_msg" />
</body>
</html>
</xsl:template>
</xsl:stylesheet>

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'); 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'); xmlwriter_write_element ($memory,'title', 'Test WAP Document');
xmlwriter_end_element($memory); xmlwriter_start_element($memory,'body'); xmlwriter_start_element($memory,'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); xmlwriter_end_element($memory); xmlwriter_end_element($memory); 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>
