Hi,

I need to read the following RSS news link https://www.20minutos.es/rss/ourense/
and represent in visualization, can someone help me?

Hi Daponte,


this one works for us 

Code:

require('socket.http')

socket.http.TIMEOUT = 15

local data = socket.http.request('http://www.rtlnieuws.nl/service/rss/nederland/index.xml')
--log(data)

itemtag = false
result = {}

-- callback for tag start � -- create new storage in result table for each <item> tag
function starttag(parser, tag)
 if tag == 'item' then
   itemtag = true
   table.insert(result, {})
 end
 currtag = tag
end

-- callback for tag end
function endtag(p, tag)
 if tag == 'item' then
   itemtag = false
 end
 currtag = nil
end

-- callback for character data
function cdata(parser, text)-- check if parser is inside of <item> and either in <title> or <description>
 if itemtag and currtag then
   if currtag == 'title' then
     result[ #result ].title = text
   elseif currtag == 'description' then
     result[ #result ].description = text
   end
 end
end

-- create parser
lxp = require('lxp')
parser = lxp.new({
   StartElement = starttag,
 EndElement = endtag,
   CharacterData = cdata,
 })

-- sample data
ldata = [[

if parser:parse(data) then
--log(result)
else
 log('parse failed')
end

if true == true then

 os.sleep(4)
 grp.update('6/1/11', (result[1].description))
 os.sleep(9)
