Exemples
The following example will echo back an xml file using the basic event based parser. Currently, (at least in the version of PHP5 I'm using) it will skip The XML declaration and the Doctype declaration--they don't seem to be captured by the default handler.
<?php
echo "<pre>";
$file = "test.xml";
echo $file."\n";
global $inTag;
$inTag = "";
$xml_parser = xml_parser_create();
xml_parser_set_option($xml_parser, XML_OPTION_CASE_FOLDING, 0);
xml_parser_set_option($xml_parser, XML_OPTION_SKIP_WHITE, 1);
xml_set_processing_instruction_handler($xml_parser, "pi_handler");
xml_set_default_handler($xml_parser, "parseDEFAULT");
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "contents");
if (!($fp = fopen($file, "r"))) {
if (!xml_parse($xml_parser, $data, feof($fp))) {
die( sprintf("XML error: %s at line %d",
xml_error_string(xml_get_error_code($xml_parser)),
xml_get_current_line_number($xml_parser)));
}
}
while ($data = fread($fp, 4096)) {
if (!xml_parse($xml_parser, $data, feof($fp))) {
die( sprintf("XML error: %s at line %d",
xml_error_string(xml_get_error_code($xml_parser)),
xml_get_current_line_number($xml_parser)));
}
}
xml_parser_free($xml_parser);
function startElement($parser, $name, $attrs) {
global $inTag;
global $depth;
$padTag = str_repeat(str_pad(" ", 3), $depth);
if (!($inTag == "")) {
echo ">";
}
echo "\n$padTag<$name";
foreach ($attrs as $key => $value) {
echo "\n$padTag".str_pad(" ", 3);
echo " $key=\"$value\"";
}
$inTag = $name;
$depth++;
}
function endElement($parser, $name) {
global $depth;
global $inTag;
global $closeTag;
$depth--;
if ($closeTag == TRUE) {
echo "</$name>";
$inTag = "";
} elseif ($inTag == $name) {
echo " />";
$inTag = "";
} else {
$padTag = str_repeat(str_pad(" ", 3), $depth);
echo "\n$padTag</$name>";
}
}
function contents($parser, $data) {
global $closeTag;
$data = preg_replace("/^\s+/", "", $data);
$data = preg_replace("/\s+$/", "", $data);
if (!($data == "")) {
echo ">$data";
$closeTag = TRUE;
} else {
$closeTag = FALSE;
}
}
function parseDEFAULT($parser, $data) {
$data = preg_replace("/</", "<", $data);
$data = preg_replace("/>/", ">", $data);
echo $data;
}
function pi_handler($parser, $target, $data) {
echo "<?$target $data?>\n";
}
echo "</pre>";
?>
Exemple de structure XML
Ce premier exemple affiche la structure de l'élément de début dans un document avec indentation.
Exemple #1 Afficher une structure XML
<?php
$file = "data.xml";
$depth = array();
function startElement($parser, $name, $attrs)
{
global $depth;
for ($i = 0; $i < $depth[$parser]; $i++) {
echo " ";
}
echo "$name\n";
$depth[$parser]++;
}
function endElement($parser, $name)
{
global $depth;
$depth[$parser]--;
}
$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
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("XML error: %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);
?>
