RSS example breaks with other feeds

[Jellicle]

The RSS example stack on the support pages uses a slashdot feed; I'm getting errors with all other feeds I've tried. Is the example stack hard-wired for that feed?

(BTW I'm brand new to working with RSS/XML. Go easy on me )

Jellicle,

Got a link to that stack?

I also need some help on this.

I have downloaded the stack available on this page: (sorry...for some reason I can't post web links!!!...but it is lesson 19173-Intermediate-RSS-Feeds

I have changed the RSS feed located at the top of the card script and tried it with a BBC feed but no feed appears.

I think it has something to do with the feed format etc and this: revXMLChildNames(tTreeID, "RDF", return, "item", true)

BUT, as a complete noob I could be looking in the wrong direction.

Any help would be appreciated (remember...new to LiveCode)

Many thanks

Just discovered this post.

We had the same problem earlier this year with the tutorial. Delving into the XML feed format for the RSS content was the key for us. The solution proved straightforward in the end - replacing the "RDF" parameter in revXMLChildNames(tTreeID, "RDF", return, "item", true) with "rss/channel".

This will give revXMLChildNames(tTreeID, "rss/channel", return, "item", true) so will happily read through RSS feeds such as those from the BBC.

It would be useful if the tutorial had made some reference to different RSS formats to assist the unwary!

Hope this is helpful and proves worthwhile.

Didn't work for me either.

This basic piece of code works for me.
Got the explanation from http://activethought.net/livecode-server/xml/

Code: Select all

on mouseUp
    get url "http://www.nu.nl/rss/Algemeen" // Put here your URL
    put it into myXML
    put revCreateXMLTree(myXML, false, true, false) into tTree
    if tTree is not an integer then
        answer "Error with revCreateXMLTree !"
        exit mouseUp
    end if
    --
    // we can directly access nodes
    put revXMLNodeContents(tTree, "rss/channel/title") && "-" && revXMLNodeContents(tTree, "rss/channel/description") into tTitleAndDescr -- this will out put sites title and description
    put tTitleAndDescr & " .... " into RSSText
    --
    put revXMLChildNames(tTree, "rss/channel/", return, "item", true) into recentPosts
    repeat for each line aPost in recentPosts
        put revXMLNodeContents(tTree, "rss/channel/" & aPost & "/title") into postTitle
        put revXMLNodeContents(tTree, "rss/channel/" & aPost & "/link") into postLink
        put postTitle & " .... " after RSSText
    end repeat
    --
    answer RSSText
end mouseUp
