URL: open() works, but not loadStrings()
Dec 6th, 2009, 1:34pm  
I want to get the HTML code of a website.
The getStrings() function works not for all ?
But nevertheless I can open the page...?
I have no clue.


String url = "http://news.google.fr/nwshp?hl=fr&tab=wn";
String [] htmlarray;
open("http://news.google.fr/nwshp?hl=fr&tab=wn");
htmlarray  = loadStrings(url);

--->
gives the following error: The file "http://news.google.fr/nwshp?hl=fr&tab=wn" is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable.

this is not how you supposed to use it. open is used for executing other applications . http://processing.org/reference/open_.html

for opening a website you use link() but not in this case.
You need to parse the website to get the information you are looking for.
Right now you are loading the whole website, or at least try.
What information do you expect to load into your htmlarray ?

you can use proXML to parse the RSS feed.

some other people might be able to give you some more information on how exactly to do that.
