How can I parse 'document.getElementById' values in Cocoa?

Question

I'm having a hard time to figure out how to get the value from the below code.

document.getElementById('today-details-1').value = '41';
document.getElementById('today-details-2').value = '30';

I'm having my application making a NSURLConnection and it is receiving the contents of the page which are basically 5 more lines like the ones above.

I want to be able to get the value for each of the elements. How would I accomplish this?

I tried nodesForXPath but can't get that to work as this is not really a xml page.

Maybe something like this:

NSString *oneString = [myWebView stringByEvaluatingJavaScriptFromString:@"document.getElementById('today-details-1').value"];
