Scan a web page?

[Sicter]

Hi all,
What I'd like to do is scan a webpage (every 10 minutes or so) looking for a certain text. If text is found Girder should send an event (OSD or whatever, that part is easy). All this preferably without a browser open. Any of you girder gurus out there that can help me accomplish this?
TIA

using the luasockets extensions which are included with g3.3. the version of luasockets is 1.4 and you can find the documentation on the web.

also doable using luacom and the DOM object.

use winluaex for timer to check.

note: all this is much easier in g4.

Thanks Mike.

I would really appreciate if anybody could walk me through the process of setting this up as I'm unexperienced in writing scripts. I've found some stuff on the web but for a Lua newbie it was all over my head.

TIA

I am sorry but I don't time to do this in detail you could try in Girder 4

url = "http://www.promixis.com"

s = win.DownloadURLToMemory (url)

print (s) -- make sure we got the page

Ok, I've decided to use cURL to fetch the site and to save it as a text file. So no LUA needed there. Half job done. But now I need to learn how to serch for a string inside this file, and if found - trigger an event. I really hope someone can chime in for this one. I'd be most grateful.

Can you post a copy of the file that you produce?

Assuming it's a text or html file, it should be easy to have lua read the file, line by line, and see if it finds a search string you specified.

I think something like this should work:

  filedirectory     = "C:\\Program Files\\girder\\" 
  filename          = "test.txt" 
  readfilename      = filedirectory .. filename 

  fout = readfrom(readfilename) 

  if not fout then 
     print ("File does not exist.") 
  else 
    while 1 do 
        templine = read(fout) 
        if not templine then break end 
        if strfind (templine, 'your search terms') then 
           -- place the event you want to trigger here
           -- like TriggerEvent('Myevent',18)
           break
        end
     end 
  end 
  
  readfrom()
