Enclosure tag images

[nikola]

1) Script Title:Advanced ajax RSS Ticker

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...ajax/index.htm

3) Describe problem: Enclosure tag does not show images

Hi there!

Does anyone know how can i include pictures that are in enclosure tags - something like this.

<enclosure url="url-of-image" type="image/gif"/>

To be valid* in HTML they would have to be converted to img or possibly object tags. This could be done via regular expression possibly in either one of the PHP files or in the rssticker.js file. Probably the latter would be easiest because it's at that point that the content first becomes a bonifide string.

The img tag is more widely supported. So try that. In rssticker.js replace the initialize function with this one:

rssticker_ajax.prototype.initialize=function(){ 
if (this.ajaxobj.readyState == 4){ //if request of file completed
if (this.ajaxobj.status==200){ //if request was successful
var xmldata=this.ajaxobj.responseXML
if(xmldata.getElementsByTagName("item").length==0){ //if no <item> elements found in returned content
document.getElementById(this.tickerid).innerHTML="<b>Error</b> fetching remote RSS feed!<br />"+this.ajaxobj.responseText
return
}
var instanceOfTicker=this
this.feeditems=xmldata.getElementsByTagName("item")
//Cycle through RSS XML object and store each peice of an item inside a corresponding array
for (var i=0; i<this.feeditems.length; i++){
this.title[i]=this.feeditems[i].getElementsByTagName("title")[0].firstChild.nodeValue
this.link[i]=this.feeditems[i].getElementsByTagName("link")[0].firstChild.nodeValue
this.description[i]=(this.feeditems[i].getElementsByTagName("description")[0].firstChild.nodeValue).replace(/enclosure/gi, 'img').replace(/\burl=/gi, 'src=')
this.pubdate[i]=this.feeditems[i].getElementsByTagName("pubDate")[0].firstChild.nodeValue
}
document.getElementById(this.tickerid).onmouseover=function(){instanceOfTicker.mouseoverBol=1}
document.getElementById(this.tickerid).onmouseout=function(){instanceOfTicker.mouseoverBol=0}
this.rotatemsg()
}
}
}

This is just an educated guess as I don't have any feeds that I know have enclosure tags for images in them handy to test on. As long as the paths to the images are absolute, it should (barring typos or failure in logic on my part) work. If you want more help give us the URL to the feed with these enclosures in it.


*enclosure is valid in RSS, just not in HTML.

nope, that didn't work.

The rss i must show with images is http://auto1.bg/public/rss/news_en.xml.

I think you would need an updated version of lastRSS.php (assuming there's one and it can parse the enclosure tag) and then some modifications to the bridge.php and rssticker.js (different than the one I suggested as the enclosure tag is not inside the description tag).

This is not a project I would want to undertake at this time, sorry.

Alternatively, there are other ways to grab feeds. The Google Feed API:

http://code.google.com/apis/feed/

might be able to be used for this. At least it's likely to be more up to date.

You could also take a look at some of the results of this search:

This also looks promising:
