iOS Detect Name in HTML and send Local Notification

[newtoiphonesdk]

Here is what I am wondering if it is even possible to do. Our app incorporates a changing list of duties. The list is shown in a webview that is edited server side each week. I would like to have the user type in their name on first run ONLY, and have the app detect if the name is found on the html. If it is found, it would pop up a local notification that simply tells them to check the list, as they have a duty to perform that week. Is this possible to do? I was thinking that what they type in is stored as a permanent string (?) and then have enough parsing of the HTML to search for the name. If there is a match, it pops up the notification. Does that sound about right, and how could I store the string, and only prompt the dialog to type in their name on first run?
