Gunakan file XML yang sama, tetapi dengan cara yang berbeda untuk menampilkan data XML:
<?php
$parser=xml_parser_create();
function start($parser,$element_name,$element_attrs)
{
switch($element_name)
{
case "NOTE":
echo "-- Note --<br />";
break;
case "TO":
echo "To: ";
break;
case "FROM":
echo "From: ";
break;
case "HEADING":
echo "Heading: ";
break;
case "BODY":
echo "Message: ";
}
}
function stop($parser,$element_name)
{
echo "<br />";
}
function char($parser,$data)
{
echo $data;
}
xml_set_element_handler($parser,"start","stop");
xml_set_character_data_handler($parser,"char");
$fp=fopen("test.xml","r");
while ($data=fread($fp,4096))
{
xml_parse($parser,$data,feof($fp)) or
die (sprintf("XML Error: %s at line %d",
xml_error_string(xml_get_error_code($parser)),
xml_get_current_line_number($parser)));
}
xml_parser_free($parser);
?>
$parser=xml_parser_create();
