Can anyone recommend a feeder that will display RSS feeds in HTML form on an HTML web page, not a PHP one?

2 Mar 12, 2005 10:51

thats a tough one, and here is why ...

typically the feeds are actually parsed out of an external file, thats been written to by the feed reader OR theyre inserted like they would be if they were piped to a temp file first. Either way, you need something to do the work. and plain ole' HTML cannot do it.

If you are deadset against <?php ... are you able to use, and open to using a server side include (CGI include)? if so, and if you have access to creating an .htaccess i can show you how to make cgi callouts, like SSI's available within .html files. From there you just need the feed reader, at that point the next question is are you able to have the feed reader itself be php based?

Why do you especially want html output? - is it portability or search engine friendly pages or something else - because as whoo points out it's not an easy matter in itself.

nope, I think you misunderstand me.

the output isnt the hitch -- its the fact that he/she wants to run scripts, be they perl/CGI/PHP using a plain ole' HTML file, HTML is not a scripting language :)

Server side includes are the way to go in this case, fix up an .htaccess that allows html files to be be server parsed, like so:

AddType text/x-server-parsed-html .html


AddHandler server-parsed .html

and You just turned a plain ole HTML file into something that can use cgi.

After that, use nearly any feedreader that writes to an external file, there are more than a few of them. I can provide links if needed.

then call the feed using a simple include within the .html file ...

<!--#include virtual="/myfeed/feed.txt" -->

voila done :)

Yes, I want HTML output for search engine friendly pages. Unfortunately, currently the page I am going to be displaying the feeds on is an shtml page, and can't be modified to php until the entire script is written for php.

The page I am using is running SSI; at least I know it was, but I have just got a new computer, and I am having problems getting some scripts to display, I think usually ones that employ JavaScript somewhere.

.shtml pages are server parsed and using SSI includes you can insert RSS feeds... no need to worry about switching that over to php unless you want to for another reason..

ill dig around in my files and give you the link to the old RSS feeded I used to use -- it was fairly easy to set up, and ...

well here is the original script :

I managed to locate a souped up version of that somewhere else, but that version should do you just fine. Set up properly, Its going to create a page with the feed outputs, then you just include that page into your .shtml page using the include stuff I showed you above.

yes, that would be it :) it's a great script, worked for me flawlessly -- hope it helps you :)

Any idea how I would modify the feed to display the date of posting as well as the titles of each post?

11 Mar 16, 2005 20:59

i would have to re-install it and take a look myself .. i'm not using it currently so off the top of my head no ... but i can point to you to PHP's date function:

And al of that depends on whether or not you want the date it's put on your site or the date you snagged it from the other site, or the date it was first posted to the original site. Just those minor details :)

Here is the code for the two files:


  // OK this file will get the headlines from Slashdot... 
  include("rdf.php"); // Include out RDF util class


<title>RSS News Feed Example</title>
td            { font-family: Verdana; font-size: 8pt }
td.title      { font-family: Verdana; font-size: 10pt }
A:link        { background-color: transparent; color: #0000ff; text-decoration: none; }
A:visited     { background-color: transparent; color: #0000ff; text-decoration: none; }
A:hover       { background-color: transparent; color: #ff0000; text-decoration: none; }
A:active      { background-color: transparent; color: #ff0000; text-decoration: none; }

  // This will grab the news feed, start at item 0 (the first item) and pull 10 items.  It is refreshed every 6hrs.
  echo getfeed('', '0', '10', '360');





// Based upon the script located at the URL..

// Modified by Axe ( on October 2nd, 2003.
// [Changes]
//    - All functions now "return" a value instead of echoing it directly.
//    - basename($url) changed to md5($url) to prevent file overwriting
//      when two sites share an identical filename for their RSS feeds.
//    - Added the $dirname variable so you can store the RSS feeds in a
//      separate directory and they're not cluttering up your main script
//      directory (and so you don't have to chmod 777 your main script
//      directory.
//    - Modified the output a little bit to send back a table.
//    - Added $sepcolor variable for line separator between headlines
//    - Added the getfeed() function so that we didn't have to have half a
//      dozen lines in the main script to call the feed.
//    - Added $useremail variable.  Set this to a contact E-Mail address.  This
//      is sent out as part of the User-Agent, so that people you are grabbing
//      feeds from know how to contact you if they so desire.

// Config some variables..
$dirname = 'rss/';  // This is the directory where the news feed files are stored - Remember to CHMOD 777 this directory.

My knowledge of PHP is almost nonexistent, so I don't even know which file I would need to modify. The date I would be after is the date the post was originally posted to the original site.

13 Mar 16, 2005 22:01

well, first question then is that date available somewhere? if so where?

14 Mar 16, 2005 22:21

Initially, I would be using a b2e blog. The date is published in each post, so I'm sure it's available somewhere.
