Set a function to be called when the parser finds an external entity in the XML document in PHP
Description
The following code shows how to set a function to be called when the parser finds an external entity in the XML document.
Example
//w w w.j a v a 2 s .co m
<?php
$parser=xml_parser_create();
function char($parser,$data){
echo $data;
}
function ext_ent_handler($parser,$ent,$base,$sysID,$pubID){
echo "$ent<br />";
echo "$sysID<br />";
echo "$pubID<BR />";
}
xml_set_character_data_handler($parser,"char");
xml_set_external_entity_ref_handler($parser, "ext_ent_handler");
$fp=fopen("test.xml","r");
while ($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);
?>
The following code is for test.xml.
<?xml version="1.0" encoding="UTF-8"?>
<note>/*ww w . j av a 2 s . c om*/
<to>Work</to>
<from>Home</from>
<heading>Reminder</heading>
<body>This is a message.</body>
