[Laszlo-user] Open a socket and read/write text

[Evaldas Taroza]

Hello,

Thanks Henry for the pointer. Indeed I need a TCP socket. Normal Dataset 
will not do the job, I think.

When you say to use Flash API, how do I do it? I mean, in Flash I 
suppose there is another programing language, like ActionScript, so how 
do I do it from within OL then?

And when you say that Flash API is not officially supported by OL can it 
be that my app will eventually break, when you change somethings inside OL?

A bit about my problems:
As I told you I am taking my first steps with OL. So I decided to write 
some simple chat program, which would support a very small subset of 
XMPP. So as a start I need to send to the chat server the following text:
<?xml version='1.0' encoding='UTF-8'?>
   <stream:stream
     to='localhost'
     xmlns='jabber:client'
     xmlns:stream='http://etherx.jabber.org/streams'
     version='1.0'>

And the server responds to something similar as well. As you can see it 
is not a well-formed XML document, so I need to treat it as text and 
parse it. All the subsequent communication happens with well-formed XML 
snippets.

Do you think it's possible?
