Créer un document XML basique

Cet exemple montre comment utiliser XMLWriter pour créer un document XML en mémoire.

Exemple #1 Créer un document XML basique

<?php

$xw
= xmlwriter_open_memory();
xmlwriter_set_indent($xw, 1);
$res = xmlwriter_set_indent_string($xw, ' ');

xmlwriter_start_document($xw, '1.0', 'UTF-8');

// Un premier élément
xmlwriter_start_element($xw, 'tag1');

// Attribut 'att1' pour élément 'tag1'
xmlwriter_start_attribute($xw, 'att1');
xmlwriter_text($xw, 'valueofatt1');
xmlwriter_end_attribute($xw);

xmlwriter_write_comment($xw, 'ceci est un commentaire.');

// Début d'un élément enfant
xmlwriter_start_element($xw, 'tag11');
xmlwriter_text($xw, 'Ceci est du texte, ä');
xmlwriter_end_element($xw); // tag11

xmlwriter_end_element($xw); // tag1


// CDATA
xmlwriter_start_element($xw, 'testc');
xmlwriter_write_cdata($xw, "Ceci est du contenu cdata");
xmlwriter_end_element($xw); // testc

xmlwriter_start_element($xw, 'testc');
xmlwriter_start_cdata($xw);
xmlwriter_text($xw, "test cdata2");
xmlwriter_end_cdata($xw);
xmlwriter_end_element($xw); // testc

// Une instruction de traitement
xmlwriter_start_pi($xw, 'php');
xmlwriter_text($xw, '$foo=2;echo $foo;');
xmlwriter_end_pi($xw);

xmlwriter_end_document($xw);

echo
xmlwriter_output_memory($xw);

L'exemple ci-dessus va afficher :

<?xml version="1.0" encoding="UTF-8"?>
<tag1 att1="valueofatt1">
 <!--ceci est un commentaire.-->
 <tag11>Ceci est du texte, ä</tag11>
</tag1>
<testc><![CDATA[Ceci est du contenu cdata]]></testc>
<testc><![CDATA[test cdata2]]></testc>
<?php $foo=2;echo $foo;?>
