I guess I am looking for some kind of socket
function in JavaScript (like fsockopen() in PHP).
Is there such thing?

Search for 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.
