Using an XSL stylesheet together with an ASP.NET XML control can be a great way to format the output of a database query. For instance a cool implementation is that you can embed an XML control within a ListView control so that you can output a tree-like structure in your ListView rather than the standard tabular structure.
One surprisingly tricky thing is setting up a call to a JavaScript function within your XSL stylesheet that passes data from your database query dynamically. Unlike traditional ASP/ASP.NET you cannot directly output your database variable in your XSL markup (ie: along the lines of: Text='<%# Eval(“SomeData”) %>’). Instead, you first need to assign the dynamic data to a variable and then you need to use that variable to format your JavaScript call.
