If someone knows how to do this, please let me know. Most feeds generated are too large to be practical to work with, so am trying to find a solution.
Ok lets clear this up amd maybe i can help you... Are you trying to limit the amout of feeds shown in your ebay affiliate feed? Are you displaying the feed on your own site? If so how are you displaying this feed? Are you using a javascript or php or what?
Hey Dude, What I am trying to achieve is limiting the number of eBay listings displayed in each eBay rss feed I generate. Most feeds I am generating are very long.
The only thing you can control is if you were posting them to your site however if you trying to send them through a reader you can also limit them. If your posting them to your site for display they can be easy to control. So, let me know where your trying to limit them. On your site display on your reader? I guess I'm just not undersdanding were you would like to limit them. Also, you do know your RSS Ebay feed is no more them custom search.

Ok lets try this... change all of the red areas to fit your needsand you should be fine. Let me know if it works... Also when you finish I have a question for you about your existing feeds. Do you have your own feeds for your site? <?php // ( Generates HTML from a RSS feeds ) // // Licensed Under the Gnu Public License // // Here are the feeds - you can add to them or change them $RSSFEEDS = array( 0 => "http://yourdomain.com/myrss.xml", ); // // Makes a pretty HTML page bit from the title, // description and link // function FormatRow($title, $description, $link) { return <<<HTML <!-- RSS FEED ENTRY --> <p class="feed_title"></p> <p class="feed_description">$description</p> <a class="feed_link" href="$link" rel="nofollow" target="_blank">Read more...</a> <hr size=1> <!-- END OF RSS FEED ENTRY --> HTML; } // we'll buffer the output ob_start(); // Now we make sure that we have a feed selected to work with if (!isset($feedid)) $feedid = 0; $rss_url = $RSSFEEDS[$feedid]; // Server friendly page cache set every 10 min $ttl = 60*10;// 60 secs/min for 60 minutes = 1 hour(360 secs) $cachefilename = md5($rss_url); if (file_exists($cachefilename) && (time() - $ttl < filemtime($cachefilename))) { // We recently did the work, so we'll save bandwidth by not doing it again include($cachefilename); exit(); } // Now we read the feed $rss_feed = file_get_contents($rss_url); // Now we replace a few things that may cause problems later $rss_feed = str_replace("<![CDATA[", "", $rss_feed); $rss_feed = str_replace("]]>", "", $rss_feed); $rss_feed = str_replace("\n", "", $rss_feed); // If there is an image node remove it, we aren't going to use // it anyway and it often contains a <title> and <link> // that we don't want to match on later. $rss_feed = preg_replace('#<image>(.*?)</image>#', '', $rss_feed, 1 ); // Now we get the nodes that we're interested in preg_match_all('#<title>(.*?)</title>#', $rss_feed, $title, PREG_SET_ORDER); preg_match_all('#<link>(.*?)</link>#', $rss_feed, $link, PREG_SET_ORDER); preg_match_all('#<description>(.*?)</description>#', $rss_feed, $description, PREG_SET_ORDER); // // Now that the RSS/XML is parsed.. Lets Make HTML ! // // If there is not at least one title, then the feed was empty // it happens sometimes, so lets be prepared and do something // reasonable if(count($title) <= 1) { echo "No news at present, please check back later.<br><br>"; } else { // OK Here we go, this is the fun part // Well do up the top 50 entries from the feed for ($counter = 1; $counter <= 50; $counter++ ) { // We do a reality check to make sure there is something we can show if(!empty($title[$counter][1])) { // Then we'll make a good faith effort to make the title // valid HTML $title[$counter][1] = str_replace("&", "&", $title[$counter][1]); $title[$counter][1] = str_replace("'", "'", $title[$counter][1]); // The description often has encoded HTML entities in it, and // we probably don't want these, so we'll decode them $description[$counter][1] = html_entity_decode( $description[$counter][1]); // Now we make a pretty page bit from the data we retrieved from // the RSS feed. Remember the function FormatRow from the // beginning of the program ? Here we put it to use. $row = FormatRow($title[$counter][1],$description[$counter][1],$link[$counter][1]); // And now we'll output the new page bit! echo $row; } } } // Finally we'll save a copy of the pretty HTML we just created // so that we can skip most of the work next time $fp = fopen($cachefilename, 'w'); fwrite($fp, ob_get_contents()); fclose($fp); // All Finished! ob_end_flush(); // Send the output to the browser ?>
I appreciate the help dude. That code seemed to limit the eBay listings in the feed, but I get this at the end of it: Warning: fwrite(): supplied argument is not a valid stream resource in /home/account/public_html/modules/content.module(14) : eval()'d code on line 109 Warning: fclose(): supplied argument is not a valid stream resource in /home/account/public_html/modules/content.module(14) : eval()'d code on line 110 Code (markup):
Your url is not completely valid... Try on you know that works. You knnow not one that you have generated. Find a news feed from another page and try to phase it and see if its ok. Or wait ... are you using aJoomla or a CMS ? It looks like you va e pointed this script to a mod?
The same feed works fine with the other RSS parser code I was using (just doesn't limit it) Yeah the feed is being parsed on a CMS page.
