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 = [[
