I've just debugged and optimized my xmlparser.
gdemartini's xml-example generates this structure:
stdClass Object
(
[FORM] => stdClass Object
(
[SECTION] => stdClass Object
(
[NAME] => Data
[EDITFIELD] => stdClass Object
(
[LABEL] => Text:
[NAME] => poll_text
[LENGTH] => 255
[SIZE] => 56
[REQUIRED] => T
)
[MEMOFIELD] => stdClass Object
(
[LABEL] => Options
[NAME] => options
[COLS] => 56
[ROWS] => 5
[REQUIRED] => T
)
)
)
)
the moldb example generates this structure:
stdClass Object
(
[MOLDB] => stdClass Object
(
[MOLECULE] => Array
(
[0] => stdClass Object
(
[NAME] => Alanine
[SYMBOL] => ala
[CODE] => A
[TYPE] => hydrophobic
)
[1] => stdClass Object
(
[NAME] => Lysine
[SYMBOL] => lys
[CODE] => K
[TYPE] => charged
)
)
)
)
here is the code. enjoy!
class XMLParser {
var $path;
var $result;
function cleanString($string) {
return trim(str_replace("'", "'", $string));
}
function XMLParser($encoding, $data) {
$this->path = "\$this->result";
$this->index = 0;
$xml_parser = xml_parser_create($encoding);
xml_set_object($xml_parser, &$this);
xml_set_element_handler($xml_parser, 'startElement', 'endElement');
xml_set_character_data_handler($xml_parser, 'characterData');
xml_parse($xml_parser, $data, true);
xml_parser_free($xml_parser);
}
function startElement($parser, $tag, $attributeList) {
$this->path .= "->".$tag;
eval("\$data = ".$this->path.";");
if (is_array($data)) {
$index = sizeof($data);
$this->path .= "[".$index."]";
} else if (is_object($data)) {
eval($this->path." = array(".$this->path.");");
$this->path .= "[1]";
}
foreach($attributeList as $name => $value)
eval($this->path."->".$name. " =
'".XMLParser::cleanString($value)."';");
}
function endElement($parser, $tag) {
$this->path = substr($this->path, 0, strrpos($this->path, "->"));
}
function characterData($parser, $data) {
if ($data = XMLParser::cleanString($data))
eval($this->path." = '$data';");
}
}
