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;?>
