I would like to connect a georss enabled feed to the Virtual Earth block. My RSS format includes the geocoordinates within the following tags:
<georss
oint>45.6147 -122.05351</georssoint>
Is there a simple way to get Popfly to read the first value as the lat and the second value as the longitude?
Thanks.

Hi AndyS,
The URL is this: http://feeds.feedburner.com/DraftROEsGEORSS. My problem is that the lat-long data is not expressed in separate lat-long tags, as the existing GeoRSS popfly modules seem to require. Any help would be appreciated. Thanks!
So the lat/long is separated by a space in that case you could modify the geo rss to fetch the value of <georssoint> and then use the split method to get the values.
var geoPoint = itemNode.selectSingleNode("georss:point")? itemNode.selectSingleNode("georss:point").text : "";
var geoPoints = geoPoint.split(" ");
var lat = geoPoints[0];
var lon = geoPoints[1];
I've made those changes and shared a block called GeoRSS for Seldom (http://www.popfly.ms/users/Andy/GeoRSS+for+Seldom.details) which should work with your RSS feed, if not post back or comment on the project:-).
Hope it helps!
Thanks AndyS, I don't think I would have figured that out in a million years.
Now, if I may further indulge your brilliance, what I need to do is specify the item title link, so it become clickable in the pushpin window. Here's how far I got (not real far). Do you have any thoughts on how to accomplish this? Thanks much. - Seldom Heard

Andy, this project is now shared.

Thanks.
Sorry for not getting to this earlier; you can zoom into the virtual earth block and click "Advanced Mode".
Replace the code with something like:
data["VirtualEarthWithTitleLink"] = new Array();
pendingCalls["VirtualEarthWithTitleLink"] = data["GeoRSS for Seldom"].length;
for (var i=0; i<data["GeoRSS for Seldom"].length; i++)
{
try
{
var pushpinTitleText = "<a href='"+data["GeoRSS for Seldom"][i].link+"' target='_blank'>"+data["GeoRSS for Seldom"][i].title+"</a>"
var result = _Seldom_VirtualEarthWithTitleLink.addPushpin(data["GeoRSS for Seldom"][i].latitude, data["GeoRSS for Seldom"][i].longitude, "", data["GeoRSS for Seldom"][i].link, pushpinTitleText , data["GeoRSS for Seldom"][i].description);
pendingCalls["VirtualEarthWithTitleLink"]--;
}
catch (ex)
{
pendingCalls["VirtualEarthWithTitleLink"]--;
environment.reportErrorInLoop(i, ex);
}
}
Which is basically building up a HTML string to pass into the block.
I've shared the mashup as SeldomGeoMaship my user name is Andy.
Hope that works for you and answers your question.
Thanks Andy. That is not what I was hoping for. What I am looking for is a way to ensure that the title of the respective rss item in the GeoRSS feed is a clickable hyperlink. What I see now is the URL reference as the title, and the what should be the item title as the description. See below. Hope I'm making sense. Thanks. - Seldom
The title is: Should that actually be the description? If so what property should the title be?
data["GeoRSS for Seldom"]
.title
Which has some value like
Application No: CG2-27822 Applicant Name: Three Fingers Water System County: MASON
Maybe I am not understanding your questions but if you put <a href=" http://www.website.com"> RSS Link </a> it would work and be a hyper link. I think......
