PHP将将XML映射为HTML的代码实例_PHP

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

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

function endElement($parser, $name) {
global $map_array;
if ($htmltag == $map_array[$name]) {
print "";
}
}

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

$xml_parser = xml_parser_create();
// 使用大小写折叠来保证我们能在元素数组中找到这些元素名称
xml_parser_set_option($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("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);
?>
