[Google Maps API v3] Re: XML Construction for Custom Markers

[ActivityPedia]

Got it ! thank you so much Rossko and everyone who helped me found
out ! ;-)
 - I was actually having a "&" problem. I'm now catching the
"_render=" from yahoo pipes and rebuilding the url.
 - and I was also using the kml output from my pipe, instead of the
(geo)rss.
=> it now works great.
here is the code for those who would be interested in converting yahoo
pipes to google maps with custom icons.

You can also have a look on http://activitypedia.org (in French).
