Way to XML-parse data with <f n="name> </f> tags?

Sorry if this is a duplicate post, I'm new to the listserve and I'm not sure my first message made it through.... I've been trying to retro-fit sample code found at : http://www.sitepoint.com/article/php-xml-parsing-rss-1-0 to parse XML coming from a server. I'm sooo close to getting this working, but I've hit a roadblock and could use some help. To see the data I'm needing to parse, go here: http://www.librarytools.com/events/sampledata.txt. This is just sample data from the host, as it's behind a firewall. The problem I'm having is that the XML data that comes back from the host doesn't just have <eventname> </eventname> tags. It has <f n="eventname">datahere</f> tags, and I don't know how to get the XML parser to read the values using that format. (And I don't have control over the host) As a first step, I just want to retrieve the "eventname", "venuename", and "venuecity" data from within the "result" tags at the bottom of the data. I'm really hoping this is possible with PHP - - - can someone please steer me in the right direction and tell my what I should change in the below script? The $tag value is not getting a value string, due to the XML-data.... Here's my present script: <?php $insideitem = false; $tag = ""; $eventname = ""; $venuename = ""; $venuecity = ""; function startElement($parser, $name, $attrs) { global $insideitem, $tag, $eventname, $venuename, $venuecity; if ($insideitem) { $tag = $name; } elseif ($name == "RESULT") {

	    echo "found result";

$insideitem = true; } } function endElement($parser, $name) { global $insideitem, $tag, $eventname, $venuename, $venuecity; if ($name == "RESULT") { echo "result in endElement"; printf("<dt><b><a href='%s'>%s</a></b></dt>", trim($venuecity),htmlspecialchars(trim($eventname))); printf("<dd>%s</dd>",htmlspecialchars(trim($venuename))); $eventname = ""; $venuename = ""; $venuecity = ""; $insideitem = false; } } function characterData($parser, $data) { global $insideitem, $tag, $eventname, $venuename, $venuecity; if ($insideitem) {

    echo $tag;

switch ($tag) { case "EVENTNAME": $eventname .= $data; echo "got an event!"; break; case "VENUENAME": $venuename .= $data; break; case "VENUECITY": $venuecity .= $data; break; } } } $xml_parser = xml_parser_create(); xml_set_element_handler($xml_parser, "startElement", "endElement"); xml_set_character_data_handler($xml_parser, "characterData"); $fp = fopen("http://www.librarytools.com/events/sampledata.txt","r") or die("Error reading RSS data."); echo $fp; while ($data = fread($fp, 4096)) xml_parse($xml_parser, $data, feof($fp)) or die(sprintf("XML error: %s at line %d", xml_error_string(xml_get_error_code($xml_parser)), xml_get_current_line_number($xml_parser))); fclose($fp); xml_parser_free($xml_parser); ?>
