I am new to using XML and PHP for that matter. I have made some great
progress with the latter however.
My current problem is that I am trying to parse a relatively simple XML
file. The file can be found at
http://quotes.nasdaq.com/quote.dll?page=xml&mode=stock&symbol=ikn. I used
pieces of a sample file to create the following script:
$file =
$StockStuff = array();

function startElement($parser, $name, $attribs) {
    print "&lt;<font color=\"#0000cc\">$name</font>";
    if (sizeof($attribs)) {
        while (list($k, $v) = each($attribs)) {
            print " <font color=\"#009900\">$k</font>=\"<font
    print "&gt;";

function endElement($parser, $name) {
//    print "&lt;/<font color=\"#0000cc\">$name</font>&gt;";

function characterData($parser, $data) {
 print "<b>$data</b><br>";
////////////The problem lies here ---
///////////The array is not initializing prior to this statement and I am
not sure how.
array_push($StockStuff, $data);

function PIHandler($parser, $target, $data) {
    switch (strtolower($target)) {
        case "php":
            global $parser_file;
            // If the parsed document is "trusted", we say it is safe
            // to execute PHP code inside it.  If not, display the code
            // instead.
            if (trustedFile($parser_file[$parser])) {
            } else {
                printf("Untrusted PHP code: <i>%s</i>",

function defaultHandler($parser, $data) {
    if (substr($data, 0, 1) == "&" && substr($data, -1, 1) == ";") {
        printf('<font color="#aa00aa">%s</font>',
    } else {
        printf('<font size="-1">%s</font>',

function externalEntityRefHandler($parser, $openEntityNames, $base,
                                  $publicId) {
    if ($systemId) {
        if (!list($parser, $fp) = new_xml_parser($systemId)) {
            printf("Could not open entity %s at %s\n", $openEntityNames,
            return false;
        while ($data = fread($fp, 4096)) {
            if (!xml_parse($parser, $data, feof($fp))) {
                printf("XML error: %s at line %d while parsing entity %s\n",
                return false;
        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, 1);
    xml_set_element_handler($xml_parser, "startElement", "endElement");
    xml_set_character_data_handler($xml_parser, "characterData");
    xml_set_processing_instruction_handler($xml_parser, "PIHandler");
    xml_set_default_handler($xml_parser, "defaultHandler");

    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");

print "<pre>";
while ($data = fread($fp, 4096)) {
 if (!xml_parse($xml_parser, $data, feof($fp))) {
        die(sprintf("XML error: %s at line %d\n",
print "</pre>";

print "Array = $StockStuff[0]<br>\n";

Ok so the problem is that I get an error telling me I have to create the
array first. If you can't tell, what I am trying to do is push the $data
part of the XML file into an array. There is probable 100+ better ways to do
this, but I can't figure how to get the information I want. I just wanted a
simple, very simple, stock retrieval piece of script. Everything I see is
too long and complex. So I thought I would simply parse this XML file. Benn
at it for two days now. I can easily get a CSV string from YAHOO.COm, but I
am not sure how to get that into an array either.

Any help here would be great. Either completely parsing the file or some way
of pushing the $data into the array $StockStuff
