mimic pressing a button on a webpage in the backgroud, for triggering an action

Pretend you have a button on an iOS GUI. Pressing this button should now trigger a button on a webpage (which triggers an action). While doing this, the webpage should not be visible. How can I do that?

My guess is, that I read and parse the webpage, and if I've found the button action, I would trigger it somehow. Since I'm not a web programmer, I wonder how to proceed or read on for such a task.

I need this task, because there is no JSON or XML webservice on the page that would make life easier.

Many thanks for any input

Okay, let's say you've already loaded your webpage in an off-screen (or hidden) UIWebView, and the submit button on that webpage looked a bit like the following in code:

<form id="my_submit_button" etc... >

Just call the following:

NSString* javascript = @"document.forms['my_submit_button'].submit();";
[myUIWebView stringByEvaluatingJavaScriptFromString: javascript];

Hope this helps!
