此例程直接地将 XML 标签映射为 HTML 标签。
在“map_array”中未找到的元素将被忽略。
当然，此例程只针对特定的 XML 文档类型起作用。
<?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 ();
// use case-folding so we are sure to find the tag in $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 ( "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 );
?>
