Date Advance XML Coding

[jttjca]

Hi,

I have xml creating a file that pulls dates from a specific field in my application using a token, I'd like tips on how to set up the xml to look at that date and advance it 13 days. For example, if the Date in the application field is 2012-03-01, I want the file to show 2012-03-14.

Any suggestions?

Thanks,

Jon
