Listen-to xml parsing example thingie

[Trashed20]

well, i got bored one day and tried some xml parsing based on some examples i found on the web for Listen-to. don't know if anyone is interested. Prolly not very efficient but hey. I basically just made it output an image (which you can already do) but you could do anything you want with the data. comments are good

PHP Code:

<?php
$file= "http://www.listen-to.com/xml.php/trashed20";
$depth = array();
$data1=array();


function startElement($parser, $name, $attrs) {
global $name;
    global $depth;
    for ($i = 0; $i < $depth[$parser]; $i++) {}
    $depth[$parser]++;
}

function endElement($parser, $name) {
    global $depth;
    $depth[$parser]--;
}

function characterData($parser, $data) {
global $data1;
if ($data!="    "){$data1[] =$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($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);

header ("Content-type: image/jpeg");
$im = @imagecreatefromjpeg ("temp2.jpg"); 
$tc  = imagecolorallocate ($im, 255, 255, 255);
$time=date("m/d/y g:i a",$data1[11]);
$track=$data1[7];
$group=$data1[3];
imagestring ($im, 3, 230, 7, $time, black);
imagestring ($im, 3, 126, 31, $group, black);
imagestring ($im, 3, 136, 52, $track, black);
imagejpeg ($im,"",85);
?>
