Reading input via a template?

[Sam Huang]

Hello, It seems that most of the usage of Velocity is to present information, such as from an object to a web page. But what about reading information from a web page via a template file to an object? If the way to present data is like this: web = output(object, template); then can we read in data in the opposite direction: object = input(web, template); Is it possible for Velocity or other existed template engines? If it is, how to do so? Thanks!   Regards, Sam Hwang
