Siblings with Input Data Example
A list of users is defined using the XmlDataTable macro. The result is then filtered to remove all user ids less than zero.
The filtered data table is then passed to the siblings macro which generates links to other users. The links work by adding the current user id to the query string. Siblings needs a currentkey to work, so there is a default of 5 (Grumpy) given to the save buffer "userid" when it's read from the query string, which is later passed to the currentkey parameter.
