Subject: [ciapug] RSS - Text formating in <description> tag?
Message-ID: <416AB368.5000809@gmx.net>

Hello

Currently I'm playing around with RSS (version 2.0) and try to create 
some content.  With the item I use the <title>, <link> and <description> 
tags.  I was wondering if any formating of the text inside of the 
<description> tag exists.  I haven't found any discussion about it and 
the specifications don't mention anything about it either 
(http://blogs.law.harvard.edu/tech/rss#roadmap).

My guess no formating is allowed, but if it where I'd be interested in 
carrage returns (<br> or <p></p>) and bold (<b></b>).  While RSS 
validators (http://rss.scripting.com/ and 
http://feeds.archive.org/validator/) don't like the <p> and <b> tags the 
SharpReader handles it as desired.

You can use formatting if you encapsulate everything in there with a CDATA tag.
e.g.  
<description><![CDATA[Here is where you would put your formatted
information!]]></description>

Good great info.  Thanks.
The question remains if RSS Feed Readers / Aggregators do interpret 
these HTML tags.

In my opinion, they do interpret these just fine.

Message-ID: <1097763584.4687.1057.camel@fy05.dev.foo>

So, I've been fooling around trying to identify the web browser, the os
and if $MS the patch level. I've tried on with Mozilla on RHEL WS 3.x,
windows 95/98 win2k and XP... 

It's a crude function that gets the basics:


function parse_id($browser_id)
{
#
# Almost always the good stuff starts at the right paren. Convert it
# into a semi-colon to make it easier to explode the string into an
array
$new_id = str_replace("(", ";", $browser_id);
# sometimes MS doesn't use the right paren in the id string, and they
add extra stuff,
# remember embrace and extend?
# convert the right paran to a semi colon if it exits
$new_id = str_replace(")", ";", $new_id);
#echo "New id: $new_id <BR>";
# explode the values into an array
$info = explode(";", $new_id);
$cnt = count($info);
# cleanup the elements
for ($i=0;$i<$cnt;$i++){ $info[$i] = ltrim(rtrim($info[$i]));}
# element # 2 in the array is the browser identity string.
# however, mozilla and firefox put a U in there.Firefox
# identifiers end up in the elements 4 and 5, mozilla in 4,5,6
if($info[2] == 'U'){ $info[2] = "$info[4] $info[5] $info[6]";}
# windows 95/98 are reported as Windows 95 or Windows 98
# However 2000/Xp are reported as NT 5.0 or NT 5.1
# so clean it up
if($info[3]== "Windows NT 5.0"){ $info[3] = "Windows 2000";}
if($info[3]== "Windows NT 5.1"){ $info[3] = "Windows XP";}
# print out the results
for ($i=0;$i<$cnt;$i++){ echo "$i: $info[$i] <BR> ";}

return($info);

}

If anyone has any comments or ideas, I'd appreciate some feedback.

You can check for XP SP2 also by searching for SV1 (I'm not sure which
array element it would be in).  Useful for dealing with some of the
"enhancements" they've made (like file downloads)

Yeah, I've just made a bunch of tweaks to the code...

Basically what I'm gonna do is only let XP SP2 users, win2k with the
firefox or mozilla browsers, mac, linux users this particular site. If
they are running anything else, I'm gonna spit tons of messages at them
and limit the access.

I'm just not a nice person...

here's my XP SP2 user agent:
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR
1.1.4322)

At work I have to develop for NN4, so forcing a "modern" browser doesn't
seem too cruel to me :)

Subject: [ciapug] Two dynamic drop downs
Message-ID: <417D475A.8010104@raccoon.com>

Perhaps someone has a solution to this,

In a web form I have two drop downs that I need to build dynamically. 
The first drop down is a main category and the second drop down box is 
populated with appropriate options once the first drop down selection 
has been made.

This has to be done with some melding of JavaScript and PHP, but I 
haven't found the best way to solve this yet.

Just curious if anyone else had done something similar and could let me 
of a good JS script to use or psuedo code of how they solved it.

Barry recently did some javascript voodoo on the iowarealty.com web site 
to do rotating images... the PHP code builds a Javascript array, which 
loops thru the images. You could probably do something similar - load a 
javascript array, and in your onchange for the first control, have it 
load the second one from the array.

I've been really interested in doing this with php and java too.
I just haven't had the time to work on it..

Anyone got any code laying around?

ah, the joy of mixing client-side scripting with server-side scripting.

the two real options I've used (there may well be others) are either 
build the first list, then when a choice is made, resubmit/reload the 
page based on that selection.   downside: have to reload the page, save 
state, form vars, etc, etc.

otherwise, load up the first list, and create every possible second 
list, but hide it until the choice is made, then use javascript/dom foo 
to show the appropriate second list.  downside: many multiple possible 
secondary lists, long load time, having all the code in the source

six of one, half-dozen 'tother

I went with the second... in this case the select options and their 
values are not something I am concern about being seen, since it will 
you could see them in the sourse and I wasn't dealing with large numbers...

When I get a second I will clean up and comment the page/script and 
share it here.
