PHP Parsing multiple XML files

Hello,

I am trying to make a page which parses a series of XML files in order to build a schedule page. The purpose is to make it easier for the client to change schedule information by simply uploading xml files. So far, I can get the page to parse the first XML file. It also recognizes the EXISTENCE of the other two test xml files, but it does not seem to be parsing them. here is the code that I am using:

<div id="copycol">
        <h1>Calendar of Events</h1>
        <p>&nbsp;</p>
        <div class="indent">
              <p>Click an event to open that event's registration page</p>
        </div>
        <p>&nbsp;</p>
<?php
$_MONTH = array("JANUARY","FEBRUARY","MARCH","APRIL","MAY","JUNE","JULY","AUGUST","SEPTEMBER","OCTOBER","NOVEMBER","DECEMBER");
//$_CURRENTYEAR = gmdate("Y");
$_CURRENTDATE = date("m/d/Y");
$_CURRENTMONTH = gmdate("n") - 1;

/*
echo "<p>".$_CURRENTYEAR."</p>";
echo "<p>".$_CURRENTDATE."</p>";
echo "<p>".$_CURRENTMONTH."</p>";
echo "<p>".$MONTH[$_CURRENTMONTH]."</p>";
*/

      function start_tag($parser, $name, $attribs) {
            if ($name == "MONTH"){
                  echo "<div class=\"month\">";
            }
            if ($name == "MONTH_NAME"){
                  echo "<div class=\"month_name\">";
            }
            if ($name == "DATE"){
                  echo "<div class=\"date\">";
            }
            if ($name == "REGISTRATION"){
                  echo "<a href=\"registration.html\">";
            }      
            if ($name == "EVENT"){
                  echo "<div class=\"event\">";
            }
      }
      function end_tag($parser, $name) {      
            if ($name == "REGISTRATION"){
                  echo "</a>";
            }      
            else {
            echo "</div>";
            }
      }
      function tag_contents($parser, $data) {
            echo $data;
      }
      //Initialize the XML parser
      if (! ($xml_parser = xml_parser_create()) ){
            die ("Cannot create parser");
      }
      xml_set_element_handler($xml_parser, "start_tag", "end_tag");
      xml_set_character_data_handler($xml_parser, "tag_contents");
for ($i = 0;$i < 12; $i++){
      $_CURRENTYEAR = gmdate("Y");
      $_OFFSET = $_CURRENTMONTH + $i;
      if ($_OFFSET > 11){
            $_OFFSET = $_OFFSET - 12;
            $_CURRENTYEAR++;
      }
      $_CALENDARMONTH = $_MONTH[$_OFFSET];
      $_CALENDARFILE = $_CALENDARMONTH."_".$_CURRENTYEAR.".xml";
      echo "<p>".$_CALENDARFILE."</p>\n";
      if (file_exists($_CALENDARFILE)){
            echo "<p>".$_OFFSET." Offset</p>\n";
            if (!($handle = fopen($_CALENDARFILE, "r"))){
                  die("cannot open ".$_CALENDARFILE);
            }
            while ($data = fread($handle, 8000)){
                  xml_parse($xml_parser, $data, feof($handle));
            }
            fclose($handle);
      }
      xml_parser_free($xml_parser);      
}
?>
</div>

The current code outputs the first month's schedule, but then only outputs the names of the other two files and their associated $_OFFSET values. But it does not output the schedule from the XML files.

Can someone PLEASE help me with this. I have spent several hours researching this and have found nothing of help.

Thank you in advance,

~Randal

Does this line

while ($data = fread($handle, 8000)){

include the EOF of the read file, because feof only returns true on EOF.

Other than that use

$data = file_get_contents ($_CALENDARFILE);
xml_parse ($xml_parser, $data,  true);

to read and parse the file
