XML allows for repeated nodes that an array does not support in its associative index. To account for this we can use numerically indexed arrays.
$array = array(
'element' => array(
array('node' => 'some value'),
array('node' => 'some other value')
),
'key' => 'value'
);
This requires that we change the fromArray() method in the class below to check for numeric indexes and throw them away.
public function fromArray(array $array)
{
foreach ($array as $key=>$val) {
if (is_array($val)) {
if (is_numeric($key)) {
// numeric keys aren't allowed so we'll skip the key
$this->fromArray($val);
} else {
$this->startElement($key);
$this->fromArray($val);
$this->endElement();
}
} else {
$this->writeElement($key, $val);
}
}
}

Inspired in the XmlConstruct.
<?php
class XLIFFConstruct extends XMLWriter
{
var $_phrase_id=1;
public function __construct(){
$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('xliff');
$this->writeAttribute('version', '1.0');
$this->startElement('file');
$this->writeAttribute('original', 'global');
$this->writeAttribute('source-language', 'es');
$this->writeAttribute('datatype', 'plaintext');
$this->writeAttribute('date', date('c'));
$this->startElement('body');
}
public function addPhrase($source, $target){
$this->startElement('trans-unit');
$this->writeAttribute('id', $this->_phrase_id++);
$this->startElement('source');
$this->text($source);
$this->endElement();
$this->startElement('target');
$this->text($target);
$this->endElement();
$this->endElement();
}
public function getDocument(){
$this->endElement();
$this->endElement();
$this->endElement();
$this->endDocument();
return $this->outputMemory();
}
public function output(){
header('Content-type: text/xml');
echo $this->getDocument();
}
}
?>
Example:
<?php
$xliff = new XLIFFConstruct();
$xliff->addPhrase('source','target');
$xliff->addPhrase('add','a?adir');
$xliff->addPhrase('open','abrir');
$xliff->addPhrase('change','cambiar');
$xliff->addPhrase('new','nuevo');
$xliff->addPhrase('save','guardar');
echo $xliff->getDocument();
?>

setElement in the previous example does exactly the same thing as already existing writeElement.

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
{
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 => $element){
if(is_array($element)){
$this->startElement($index);
$this->fromArray($element);
$this->endElement();
}
else
$this->setElement($index, $element);
}
}
}
public function getDocument(){
$this->endElement();
$this->endDocument();
return $this->outputMemory();
}
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);
$XmlConstruct->output();
?>
Contents of the file 'XmlConstruct.class.php' :
<?php
class XmlConstruct extends XMLWriter
{
public function __construct($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' :
<?phpxml 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>

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:
<?phpxml 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">
