I guess I am looking for some kind of socket

Is there such thing?
Search for XMLHttpRequest.
http://en.wikipedia.org/wiki/XMLHttpRequest
You might want to use it to retrieve HTTP(S) documents (can be XML).
I think you cannot open pages that are not hosted in the same host
the original page (the one with the JS code) is. (I am not sure now).

You cannot use javascript to write files (assuming you want to save
them, or the results of
parsing the files). This is a security measure that every commercial
browser uses. It prevents
arbitrary scripts from reading, writing or modifying files on the
client machine.You will have to
use a server side technology like php, perl, or ruby. This can either
be done as command line
scripts or under the auspices of a web server. It sounds like you are
looking at Curl 'c'+ url.
