now, this is the script
<?php
header("Content-Type: Text/html;charset=iso-8859-1");
ini_set("default_charset","iso-8859-1");
$filename = "test.xml";
$obj->tree = '$obj->xml';
$obj->xml = "";
function startElement($parser, $name, $attrs) {
global $obj, $cade;
$cade='$test=isset($obj->tree->$name);';
if (!empty($test)){
$cade='$tmp=$obj->tree->$name;';
eval("$cade");
$cade='$arr=is_array($obj->tree->$name);';
eval("$cade");
if (!$arr){
$cade='unset($obj->tree->$name);';
eval("$cade");
$cade='$obj->tree->$name[0]=$tmp;';
eval("$cade");
$cnt = 1;
}else{
eval('$cnt=count('.$obj->tree.'->'.$name.');');
}
$obj->tree .= '->'.$name."[$cnt]";
}else {
$obj->tree .= '->'.$name;
} //fin noempty
if (count($attrs)){
eval($obj->tree.'->attr=$attrs;');
}
} // fin funcion startElement
function endElement($parser, $name) {
global $obj;
//
for($a=strlen($obj->tree);$a>0;$a--) {
if (substr($obj->tree, $a, 2) == '->') {
$obj->tree = substr($obj->tree, 0, $a);
break;
}
}
}
function characterData($parser, $data) {
global $obj;
## el eval que sigue tira errores , pero el funcionamiento de la script no se altera
@eval($obj->tree.'->data=\''.$data.'\';');
}
$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
if (!($fp = fopen($filename, "r"))) {
die("no se puede abrir entrada xml");
}
while ($data = fread($fp, 4096)) {
if (!xml_parse($xml_parser, $data, feof($fp))) {
die(sprintf("XML error: %s en linea %d",
xml_error_string(xml_get_error_code($xml_parser)),
xml_get_current_line_number($xml_parser)));
}
}
xml_parser_free($xml_parser);
print "<pre>";
print_r($obj->xml);
print "</pre>";
?>
--------------------------------------------------------------------
the result of print_r($obj->xml); is the next estructure
stdClass Object
