the sample giving not xml document , message says document bad beginning (line 1, position 1). xml document should (wikipedia):
<?xml version="1.0" encoding="utf-8" ?> <俄语>данные</俄语> edit understand file downloaded correctly , doesn't. best solution accept fact , attempt download again. example
dim success boolean = false try weatherdoc = xdocument.load("http://open.live.bbc.co.uk/weather/feeds/en/2656752/3dayforecast.rss") success = true catch ex xmlexception success = false end try loop until success and maybe ask question "why downloading garbage open.live.bbc.co.uk/weather?"
