GeoRssLayer encodeing

DarellStoick — Mon, 04 Apr 2011 15:35:07 GMT

encoding="ISO-8859-1"

Running your GeoRss example from the Silverlight API (http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#GeoRssSimple) with a url like http://www.prh.noaa.gov/ptwc/feeds/ptwc_rss_hawaii.xml

causes an error. Any suggestions for RSS Feeds with encoding="ISO-8859-1"?

Thanks

Unfortunately Silverlight doesn't support ISO-8951-1 encoding.

One option might to manage the encoding conversion by yourself by modifying the GeoRss code provided here : http://esrisilverlight.codeplex.com/
In a first time you could force the encoding to UTF-8 and check if the result is aceptable or not.

It appears your GeoRssLayer can not handle html tags.

See: http://volcanoes.usgs.gov/rss/vhpcaprss.xml

If the <b> </b> tags are removed it appears to work.

If you could expand your encoding and allow html tags this control could be useful. At this point we are finding it quite difficult to find live real world feeds that actually work.

It looks like the html tags should be encoded e.g. '>b<' instead of '<b>'.

With your URL, the following feed validator is complaining at the same line than the georsslayer:
