Use XML sockets to post to asp page

Hello,

I'm currently working with an xml script I found that retrieves television
listings off the zap2it.com website. The script opens a socket to the website
two times - the first to set up what channels and what not are displayed
and the second to get the tv listing. Then the script parses the listings.


My problem is that the script can only get the tvlistings from the current
hour on, however on the the actually zap2it page they use a form to allow
the user to select date, time, etc.

Is there anyway I can send variables (i.e. startime, date, etc) through the
xml as if they were posted on a form or any ideas how I might work around
this.

If you need the script or any more details, feel free to email me at URL.
Thanks for any help you can be.
