Quote from: breynolds13 at Mar 11, 2013, 03:41 PM@desgincouch - I'm using mxcalendar and was curious if you have every formatted the output to iCal? I'd be interested in any insight you may have as I begin this endeavor. I'm looking to create a nice feed that visitors can add to their calendar but also to share the feeds between related sites.
Thanks
BReynolds,
I have actually done this with a client site recently. It's still in the last stages of development or I'd share the link, but the basic process is as simple as creating an XML feed using the mxCalendar list view as a starting point. iCal is notoriously finicky for getting the details of your items right, so here is the basic code that I'm using.
The wrapper—goes in the content area of your main Resource. This resource should NOT use Rich Text as the tags will screw with the XML, and you should create a custom content type of "iCal" and assign it to this resource (instead of the default HTML). Also be sure your timezone settings in the XML header are set correctly (you may have to change the code below to do this).
Wrapper Code & mxCalendar call:

[[!mxCalendar? &addJQ=`0` &displayType=`list` &eventListlimit=`1000` &elEndDate=`+1 year` &tplListItem=`tplListItemICAL` &tplListHeading=`tplListHeadingICAL` &tplListWrap=`tplListWrapICAL` &tplDetail=`tplDetailICAL` &debug=`0` &sort=`startdate` &dir=`ASC`]]
END:VCALENDAR
It is important to note the custom TPLs listed in the mxCalendar call. This call is tailored to my needs, and includes a tplDetailICAL chunk that is used when the user wants to add a specific event to their calendar instead of the whole feed. This chunk is exactly the same as the tplListItemICAL chunk (see below). This call also references a BLANK chunk (tplListHeadingICAL). You create it and leave it completely blank. This keeps the XML formatting all in one place (the main Resource) so that you can view it all together and make changes easier. The tplListWrapICAL chunk contains only the mxCalendar event list placeholder ( [[+eventList]] ).
tplListItemICAL & tplDetailICAL chunks:
BEGIN:VEVENT
UID:[[+id]][[+startdate]]@example.com
DTSTAMP:[[!ical_datestamp]]T[[!ical_timestamp]]
DESCRIPTION:[[+description:replace=`<br />==\n`:replace=`http://http://==http://`]]
DTSTART:[[+startdate:date=`%Y%m%dT%H%M%S`]]
DTEND:[[+enddate:date=`%Y%m%dT%H%M%S`]]
LOCATION:[[+location_name]]
SUMMARY:[[+title]]
END:VEVENT
A few important things about the code above. First, it uses some output modifiers to edit the content flowing into it. In the Description, it strips out any
and replaces them with a newline XML character ( /n ). It also eliminates an error with double http:// prefixes that I was noticing. Also, this chunk references two tiny custom snippets ( ical_datestamp & ical_timestamp ) that are necessary to make sure that the date and time stamps are correct when a user downloads the feed/event for the first time. These snippets are below.

ical_timestamp snippet:
This is a massive amount of info, and may be more than you were looking for, but I figure it will help others who are trying to do the same thing! Good luck, and let me know if I can help further.
