Maybe write a function that returns a map containing the variables, so
instead of $socksize you'd write, $metadata?socksize or whatever.

Call that at the start of the template.  Now you have only one line,
and you can use next-match with a parameter.  Or lots of templates, but
each calling that common function at the start.

Or you can invert it and have 30 lines of preamble and then call a
function.

It's possible to make a map (or array) whose entries are functions, so
another possibility is a table-driven approach, where you look up in a
table some combination of values and call the function that's listed
there.
