Cant get rss ticker to work with google calander

The xml feed that google calendar kicks out doesn't conform to the standard as it has extra data in it.

I use a script called gcalendar.php to strip this out and provide an html output that can be used by xibo. I embed the php script in an iframe as embedded html.

Have you got a basic howto on this as I am not familiar with PHP am a school network manager have got everything working just not this bit and is driving me mad. Where do i put the gcalander.php script ??
Thanks for your quick response.

Go here http://james.cridland.net/code/google-calendar.html
Copy the script into a file named gcalendar.php
Edit the script so that it is correctly configured for your calendar - the comments in the script are your instructions.
Don't use the cache, you'll probably have more trouble than it is worth.

Save the edited gcalendar.php into a folder on your webserver.
Then call the script by embedding it in an iframe - google will help you.

I have a Google calendar as an RSS ticker using this format: https://<email address hidden>/public/basic?alt=rss&futureevents=true&ctz=America/New_York&orderby=starttime&sortorder=ascending&max-results=5

But I also had to minify the URL because I don't think XIBO likes some of the characters in the URL. So I use this as my link: http://goo.gl/x2R6j and it seems to work, although the format of the feed is inflexible. In particular, I cannot get rid of "status: confirmed" portion of each event. But it's a small price to pay. You could use an internal PHP page to parse the results.

ok I thought I should update on this. I have it working Its very dirty way of doing it. I downloaded simplepie.inc as well as jquery.newsScroll.js and
jquery.newsScroll_comments.js I then created a php file
<?php

require 'simplepie.inc';
function shorten($string, $length)
{
    // By default, an ellipsis will be appended to the end of the text.
    $suffix = '&hellip;';

    // Convert 'smart' punctuation to 'dumb' punctuation, strip the HTML tags,
    // and convert all tabs and line-break characters to single spaces.
    $short_desc = trim(str_replace(array("\r","\n", "\t"), ' ', strip_tags($string)));

    // Cut the string to the requested length, and strip any extraneous spaces
    // from the beginning and end.
    $desc = trim(substr($short_desc, 0, $length));

    // Find out what the last displayed character is in the shortened string
    $lastchar = substr($desc, -1, 1);

    // If the last character is a period, an exclamation point, or a question
    // mark, clear out the appended text.
    if ($lastchar == '.' || $lastchar == '!' || $lastchar == '?') $suffix='';

    // Append the text.
    $desc .= $suffix;

    // Send the new description back to the page.
    return $desc;
}
// Create a new class that extends an existing class
class SimplePie_Item_Extras extends SimplePie_Item {
    var $show_past_events = TRUE;

 function set_show_past_events($value = FALSE){
  $this->show_past_events = $value;

This seems to work I put in a bit of css and embeded it into the xibo and it works like a charm there is a error about strict in php but i just switched the disply errors off. I hope this helps anyone else that wants to scroll dates. Have also fixed it so that it displays all day and not a big time.

i find a free online service to minify js http://www.online-code.net/minify-js.html and compress css http://www.online-code.net/minify-css.html, so it will reduce the size of web page.
