Here I introduce you an XML Parser which creats an array and can evaluate PHP code. If the PHP code
returns a string the value of that string is added to the array.
Here is the XML
<?xml version="1.0"?>
<!DOCTYPE foo [
<!ENTITY testEnt "test entity">
]>
<document>
<foo>
<?php $a = 'foo'; $b = 4; $c = $a.$b; echo "<b>It even evaluates html
code $c</b>\n"; ?>
</foo>
<foo>hi this is text
</foo>
<foo> <?php echo $a; ?>
</foo>
</document>
Note that <?php echo $a; ?> will not echo "foo"
You might need to use include('foo.php').
And this is the Parser
<?php
$file = "xmltest2.xml";
$stack = array();
// start_element_handler ( resource parser, string name, array attribs )
function startElement($parser, $name, $attribs)
{
global $stack;
$tag=array("name"=>$name,"attrs"=>$attrs);
array_push($stack,$tag);
}
// end_element_handler ( resource parser, string name )
function endElement($parser, $name)
{
global $stack;
$stack[count($stack)-2]['children'][] = $stack[count($stack)-1];
array_pop($stack);
}
// handler ( resource parser, string data )
function characterData($parser, $data)
{
global $stack,$i;
if(trim($data))
{
$stack[count($stack)-1]['data'] .= $data;
}
}
// handler ( resource parser, string target, string data )
function PIHandler($parser, $target, $data)
{
global $stack,$i;
//PHP EVALUATION
if ((strtolower($target)) == "php") {
global $parser_file;
//eval($data); gust doesn't work if you want the
//string added to the array
$text .= '<?php '.$data.' ?>';
ob_start();
eval ('?>' . $text);
$text = ob_get_clean();
$stack[count($stack)-1]['data'] .= $text;
}
}
function defaultHandler($parser, $data)
{
}
function externalEntityRefHandler($parser, $openEntityNames, $base, $systemId,
$publicId) {
if ($systemId) {
if (!list($parser, $fp) = new_xml_parser($systemId)) {
printf("Could not open entity %s at %s\n", $openEntityNames,
$systemId);
return false;
}
while ($data = fread($fp, 4096)) {
if (!xml_parse($parser, $data, feof($fp))) {
printf("XML error: %s at line %d while parsing entity %s\n",
xml_error_string(xml_get_error_code($parser)),
xml_get_current_line_number($parser), $openEntityNames);
xml_parser_free($parser);
return false;
}
}
xml_parser_free($parser);
return true;
}
return false;
}
function new_xml_parser($file)
{
global $parser_file;
$xml_parser = xml_parser_create();
xml_parser_set_option($xml_parser, XML_OPTION_CASE_FOLDING, 0);
xml_set_processing_instruction_handler($xml_parser, "PIHandler");
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
xml_set_default_handler($xml_parser, "defaultHandler");
xml_set_external_entity_ref_handler($xml_parser, "externalEntityRefHandler");
if (!($fp = @fopen($file, "r"))) {
return false;
}
if (!is_array($parser_file)) {
settype($parser_file, "array");
}
$parser_file[$xml_parser] = $file;
return array($xml_parser, $fp);
}
if (!(list($xml_parser, $fp) = new_xml_parser($file))) {
die("could not open XML input");
}
//ERROR
while ($data = fread($fp, 4096)) {
if (!xml_parse($xml_parser, $data, feof($fp))) {
die(sprintf("XML error: %s at line %d\n",
xml_error_string(xml_get_error_code($xml_parser)),
xml_get_current_line_number($xml_parser)));
}
}
//END
xml_parser_free($xml_parser);
print("<pre>\n");
print_r($stack);
print("</pre>\n");
