iOS app - users updating wait time

Question

I am building an iPhone app in which users (or employees) will be able to go to restaurants and update/give an estimate of the waiting time at that location. To do something like this, would it be most efficient to use an XML webpage and parse the data that is currently there and update that value with the user's input then reload the XML database? Obviously any user should be able to update the site so it needs to be done from a web-server.

Also, if anyone knows of a similar example for this, that would be spectacular!

Thanks for your help,

您可以输入一个文本字段，在其中可以填充值，然后通过XML或JSON Web服务将其发送到Web服务器，其他用户可以从Web服务中查看更新。
