How about number(concat('0',$node))?

Summing is a bit harder; you may not be able to use a trick like this at all (until XPath 2).

I want to find the numeric value of a node. If the node is empty (e.g.: <taxAmount/>) I want zero. I also want zero when applying sum() to the same or a set of similar nodes.
Is there a solution to this problem other than setting a variable, check the variable = NaN, return the variable or zero?
