    Does this work with multiple feeds?

  3. Michael Shipley on 04 Jul 2008 at 5:41 am #

    Yes it does.

    Hi Michael,

    I notice this doesn’t quite work on words that have apostrophes. Say someone’s name is in the RSS feed like this … “George Bush’s agenda is to” … and someone searches for “Bush” … It’s not a match. How easy is it to implement “partial matches” in this class?

    Thanks for all of your efforts. This is a great tool.

    Hi how do you put multiple feeds into this script? can it display pictures in the feed?

    Thanks

    Oliver,

    Yes it works with multiple feeds. Yes it will display pictures if they are contained in the feed items.

    Hi
    Sorry, i tried putting in two feeds seperated by commas, but it did not work? I tried using a feed with pictures (feed://feeds.revver.com/2.0/mrss/flash/search/nokia) in the the feed items, this did not work either?
    Thanks

    Hi Michael
    Is it possible to use the paging function (http://simplepie.org/wiki/tutorial/how_to_do_item_paging?s=paging) in this great tool :-)

    Thanks

    For Oliver–

    You can get images if you remove the strip_tags function from the content:
    // $content = strip_tags($item->get_content());
    $content = $item->get_content();

    The demo strips away the tags, and hence the image data theimg tags contain.

    Your highlight function in the demo script doesn’t always handle correctly situations in which there are two highlighted words in a line.

    I get, for instance:

    Source: Time Out – London Art Critic’s Choice
    Andy “color:black;background-color:yellow”>Warhol: Other Voices, Other Rooms

    where both Warhol and Rooms are supposed to be highlighted. Notice that the opening span tag is corrupt. I’ve changed my own script as follows:

    function highlight($wordsToHighlight,$text)
    {
    $w = addslashes($wordsToHighlight);
    $w = explode(’ ‘,$w);
    foreach($w as $word)
    {

    if(preg_match(”/$word/i”, $text, $matches)) {
    $text = str_replace ($matches[0],
    ”
    . $matches[0] . ”, $text);
    }

    }
    return $text;

    This will work with both AND and OR. The term held in $matches[0] is an exact match to what is found in $text, so therefore case is preserved. Otherwise you could simp;ly use str_ireplace, without the preg_match. But then the value in $w would be substituted for the match and since all match terms are set to lower case, a lower case valu would be subsittued for the word in the text.

    Brilliant, I had been using Yahoo Pipes for this. Will look into your code to see if I can extend this for “filtering out” posts with specific words.

    I have one question, how did you do the search method that you have here as an example. I would like to implement that as well.

    thanks

    Where (what directory) should the add-on be placed in?
    All is working fine with SimpliePie on my local server, just not the addon?
    Any idea what I’m doing wrong?

  16. Chris on 01 Mar 2009 at 7:51 pm #

    I think I’m missing something. If I leave digg and type obama & economy, I don’t get anything.
    I tried cnn.com, too (simplepie’s autodiscovery still works?) and didn’t get any hits. I think there must be some results for that search.
    I also tried using this form to populate the simplepie filter add-on demo but no go.
    What should I use as the form action? I was trying to use action=”simplepie_filter.php”. Again, this seems fantastic. Just wish I could figure out how to use it.

    This tool is really great. I am going to build a website with it :)

    tom:

    you must include the simplepie class before including the simplepie_filter class.

    Hi Michael,

    Thank you, just tried the demo and this works perfectly for me. OK this is probably a silly question and mainly because I’m a newbie but I can’t get the css styling working.
    How do I style the title, date, content & images(padding) separately. I tried to add a classes to the echo lines but it either causes errors or nothing changes. So I’m asking if you could help guide me in the right direction.

    Thanks again.

  22. Pete on 09 Jan 2010 at 10:42 am #

    Span style seems to work, image padding ?

    Please help urgently.
    I am busy with a new website that has to launch in a few days and I have based everything on simplepie.
    Everything was going great until a tried to filter for a 2 letter word.

    For example: http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rss.xml
    Search for “in” or “at” and you will get no result even though it exists in the rss frequently.

    I first thought it was my programming but then when I tested it on this website I got no result either.
    Please can you help me to fix this.

  24. John on 07 Mar 2010 at 9:11 am #

    I also have an issue with searching for words that are contained within other words.
    For example “ice” is found in “iceland”
    How do you get results for “ice” only? Simplepie is space delimited so how do you filter for ” ice “?

  25. Deyan Kalchev on 11 Mar 2010 at 6:16 am #

    I try the demo, as I made rss feeds from sites in Cyrillic.
    There was no finding and coloring of words. Can this be okay and how?
