Error when converting Google Calendar

[Alexandre Passant]

Hi,

When trying to convert a calendar [1] created with Google Calendar
using fromIcal.py [2] script, I have an error with the following line:

ATTENDEE;CUTYPE=INDIVIDUAL;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;CN=Al
 exandre Passant;X-NUM-GUESTS=0:MAILTO:apassant@...

(even with --x option)

It can be solved adding X-NUM-GUEST at line 642 of the script, but I
don't think this is the most elegant way.
BTW, does this line is ok regarding iCal specs ?

Best,

Alex.

I've worked out an XSL transform which I believe will convert any iCalendar
file to an XML document that has a node for each component and property in
the input file, with attributes on component elements which are the
parameters on the properites input.

One issue, remains, however: the only way I could find to bring in the
iCalendar file was as a defined SYSTEM entity in the XSL stylesheet itself.
It's not, as near as I can tell in testing, possible to use it as the
original document, or to use the document() function because that causes
whitespace to be stripped, including the CR-LF sequence needed to determine
the end of an iCalendar property line.

If anyone has insight into how to process a text file as input in this kind
of process, please let me know. I am willing to share the stylesheet if you
like. I'm sure there are issues possibly remaining regarding quoted or
escaped characters and the like.

Right. The iCal format is text, not XML. XSLT 2.0 has an "unparsed-text()"
function that could load the file. An easier solution might be to write
a simple pre-processor in your favorite scripting language to turn the
.iCal into trivial XML. You could just wrap the whole document in a tag
or you could try to be more clever.

What prompted you to try using XSLT for parsing .ics files?

My approach to reading iCalendar has been to use python and build
JSON-shaped structures, and then convert to various XML formats
using Kid templates.

Hmm... not much documentation in those modules. I wrote
an couple items on a similar exercise involving quicken data...

Simple: I have XT at home, I don't have Python; and I wanted to see if I
could do it purely in XSLT. I've done XML-to-iCal in XSLT so this seemed
like a logical challenge. Professionally, I'm a mainframe jock, so you're
lucky I didn't just write it in COBOL <grin> - the new variants contain XML
input and output capabilities - parsing, not validating.
