Atom/RSS generator, valid feed?

theYinYeti · 05-30-2005, 05:55 AM

[EDIT:]Please jump to my next post, as I have solved part of my problem.[/EDIT]

I have written a RSS1 generator, and an ATOM generator in PHP, for giving my site's news from my "*.news" files.

Unfortunately, even though (to my knowledge) each flow is conformant to its specification, I can't read them! Firefox extension for RSS/Atom says that both are unrecognized flows, and Thunderbird just hangs when adding either.

Could someone with knowledge in those protocols/languages, help me find what is wrong?

ATOM example:
http://yves.gablin.club.fr/_php/news...path=/all.news

related HTTP headers:
Content-type: application/atom+xml
Content-Disposition: attachment; filename="all.news.atom"

RSS1 example:
http://yves.gablin.club.fr/_php/news...path=/all.news
(note: I've tried removing entirely the DOCTYPE part, and thus using the full qualified values everywhere instead of entities, but to no avail...)

related HTTP headers:
Content-type: application/rss+xml
Content-Disposition: attachment; filename="all.news.rdf"

If I can solve the Atom problem, I'll consider myself happy

and I'll remove RSS1. I won't remove Atom, though, because I like the ways it "fits" my needs.
Thanks,

Yves.

Validate them by http://feedvalidator.org/ It will show you the problems.

Thanks! I'll see what I can do from those reports.

Things have changed. Both feeds are now correct. Actually, only two changes had to be done:
- remove the duplicate ID in the items,
- replace all entity references with Unicode references (eg: & amp ; -> & #38 ; (IIRC)).

Now my site has the Atom link on the index page, both on screen and in the header. Atom still uses too new a protocol for the validator, but it's OK with me: Firefox does recognize it, and displays the orange icon in the status bar. (FYI, having the RSS1 feed is just a matter of replacing the 'news-atom.php' part with 'news-rss1.php' in the URL).

So you could say I'm happy with the result... Well, I am, except that...

In order to inform people without a feed reader, I use an XSL stylesheet to transform the raw XML feed into an HTML page with explanations. To "please" Firefox, I had to:
- send the Atom (or RSS) content in application/xml instead of application/atom+xml (or rss+xml);
- remove the forementionned header ('Content-Disposition');
- write a get.php script, to be able to choose the MIME header myself, because FF goes into "strict" mode, and does not accept the XSL file if it does not come in application/xml.

I'm not really happy with this. Is there any workaround?

Besides, even though I know that XSL works in IE, *my* XSL does not. Could someone help me spot where the problem is (or if it simply is "my" IE that does not work).

For a start, I'd like to hear from you IE users: does my feed (when you click on the "ATOM" icon) display as HTML or XML? In what version of IE?

Thanks to all testers out there. My whole PHP framework will soon be released under GPL, and it will be in part thanks to you

No IE users? Maybe my fault... I'll try and better explain what I need. It's really easy:

I'd like to know what you see when you click on one of the two links in the first post above. I need this from people using a XSL-aware browser that is *not* firefox (this one is working OK). This includes Internet Explorer 6 for example (maybe also 5.5).

You should see:

-A- either XML code like that:

Code:

<?xml version="1.0" encoding="ISO-8859-1" ?> 
  <?xml-stylesheet type="text/xsl" media="screen" href="get.php?mimetype=text/xml&...> 
- <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="http://purl...>
- <channel rdf:about="http://yves.gablin.club.fr/_php/news-rss1.php?nolog=1&filepath=...>
  <title>! Nouvelles !</title> 
  <link>http://yves.gablin.club.fr/</link> 
  <description>Nouvelles du site de Yves ET Iris</description> 
- <items>
- <rdf:Seq>
  <rdf:li rdf:resource="http://yves.gablin.club.fr/all.news/fr/20050404-233000" />
...

-B- or a nice HTML page, like that:

Code:

ATOM : ! News !

News for Iris and Yves web site

This is an Atom feed, styled with XSL and CSS

Atom is an alternative to HTML, that is dedicated to giving continuous information about ...

Please tell me if you see -A- or -B-, and with what version of what browser. Thank you.

I get XML both in Firefox (1.0.4) and Konqueror (3.3.2).

theYinYeti · 06-07-2005, 02:54 AM

??? XML in Firefox? Had I more hair left, I'd pull it out from frustration! (As for Konqueror, I'm not sure it knows about XSL)

What about IE? Opera?

Yves.

OK. There's a bug in IE, and there's a bug in Firefox. I managed to make both happy, and commited changes. For me, IE now displays XSL-generated HTML, and so does Firefox (though in local, because it has no access to internet).

Refering to my next-to-previous post, do you all see -A- or -B-? With what?
Thanks,

Yves.

Actually, Firefox proves to be bug-free in this matter!

Anyway... Any Opera user out there?
Thanks,

Yves.
