Rss Problem

**TCH-Thomas** · September 1, 2004

I finally found a rss reader I understand I think.

It works when I try the downloaded "default" code, but not when I replace the url I want to get news from (http://expressen.se/rss/nyheter'>http://expressen.se/rss/nyheter).

When I replace the default url I get this error:

Warning: fopen(http://expressen.se/rss/nyheter ): failed to open stream: HTTP request failed! HTTP/1.0 404 in /home/cpanelusername/public_html/test/index.html on line 649
could not open XML input

Does anyone know why?

Here is the original code

><?php
/*  PHP RSS Reader v1.1

   Place the URL of an RSS feed in the $file variable.
   
   The $rss_channel array will be filled with data from the feed,
   every RSS feed is different by by and large it should contain:
   
   Array {
  	 [TITLE] = feed title
  	 [DESCRIPTION] = feed description
  	 [LINK] = link to their website
  	 
  	 [IMAGE] = Array {

       [0] = Array {
         [TITLE] = item title

         [LINK = a link to the story
      	 }
       .
       .
       .
    	 }
   }
   
   By default it retrives the Reuters Oddly Enough RSS feed. The data is put into the array
   structure so you can format the information as you see fit.

Its working now, but now I bumped in to a new problem.

The text, especially the headings, are too big and I also would like to get rid of the borders around the items. Is there anyway I can change this?

My RSS test page

**borfast** · September 1, 2004

Hi Thomas.

I was going to tell you to try again, because what you were getting was a "404 page not found" error but then I tried accessing the URL and it was working.

As for your other question, see that "// output as HTML" line, near the bottom of the script? You can edit the HTML code you see after that to make the page look as you want.

**TCH-Thomas** · September 1, 2004

Thanks Raul

I tried it a little. Not going to well, but I´ll keep trying.

**borfast** · September 1, 2004

Well, here's a few tips:

change the <h2> into <h3> to make the text smaller. Or simply remove it if you want it to be the same size of the rest of the text.

If you really want to control the size, try replacing the <h2> with <span style='font-size: 1em;'>

Don't forget to close those tags!

About the borders around the items, it's simple, just replace

border=\"1\"

with

style='border: 0;'

Let me know if it does the trick

**TCH-Thomas** · September 1, 2004

Thanks Raul, that works. :-)

You rock!!! :dance:

EDIT: I thought I should change h2 to h1 to get it smaller. Now I know.

h stands for heading, it's semantic markup and can be used for accessibility purposes. But basically it means "heading 1", "heading 2" etc. That's why the heading 1 is bigger and generally gets smaller - but you can style this using css if you want =)

**TCH-Thomas** · September 1, 2004

Uh oh... I need to learn CSS then.

I will... soon. :dance:

Thanks Lisa

Can I somehow use the above code to show 2 different feeds?

What I want to do is to show both the top news and international feeds from reuters.com on same page.

**borfast** · September 2, 2004

I think you'd have to duplicate the code, Thomas.

**TCH-Thomas** · September 2, 2004

I thought it should be that easy, so I tried, but then it gave me errors for the second feed.

**borfast** · September 2, 2004

What errors did it return?

And how did you duplicate the code? It should be as easy as copying the whole block, pasting it below the one already there and changing the URL.

**TCH-Thomas** · September 2, 2004

I just copied it all, replaced the url and got this mesage:

>Fatal error: Cannot redeclare startelement() (previously declared in /home/jikrant/public_html/test/rsstest.htm:72) in /home/jikrant/public_html/test/rsstest.htm on line 226

**borfast** · September 2, 2004

I feel really stupid... :huh:

Those are functions, so of course you can't duplicate them :unsure:

Try this:

Just before the line

$xml_parser = xml_parser_create();

Put the new RSS feed URL. Something like

$file = "http://newsiteorg/feed.rss";

After that, duplicate all the code, starting from the line I mentioned before (including that line) to the end of the code.

**TCH-Thomas** · September 2, 2004

Thanks Raul. Will try it a little later today. :unsure:
