Transtypage XML -> HTML

Exemple #1 Transtypage XML -> HTML

Cet exemple remplace les balises XML d'un document par des balises HTML. Les éléments inconnus seront ignorés. Bien entendu, cet exemple sera appliqué à un type précis de fichiers XML.

<?php
$file
= "data.xml";
$map_array = array(
"BOLD" => "B",
"EMPHASIS" => "I",
"LITERAL" => "TT"
);

function
startElement($parser, $name, $attrs)
{
global
$map_array;
if (isset(
$map_array[$name])) {
echo
"<$map_array[$name]>";
}
}

function
endElement($parser, $name)
{
global
$map_array;
if (isset(
$map_array[$name])) {
echo
"</$map_array[$name]>";
}
}

function
characterData($parser, $data)
{
echo
$data;
}

$xml_parser = xml_parser_create();
// Utilisons la gestion de casse, de manière à être sûrs de trouver la balise dans $map_array
xml_parser_set_option($xml_parser, XML_OPTION_CASE_FOLDING, true);
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
if (!(
$fp = fopen($file, "r"))) {
die(
"could not open XML input");
}

while (
$data = fread($fp, 4096)) {
if (!
xml_parse($xml_parser, $data, feof($fp))) {
die(
sprintf("Erreur XML: %s at line %d",
xml_error_string(xml_get_error_code($xml_parser)),
xml_get_current_line_number($xml_parser)));
}
}
xml_parser_free($xml_parser);
?>
