XPath wildcards on node name

I want to grab a node from my XML file, the node has a prefix such as "latest_", but this may change and I'm keen for my XSLT to be as fluid as possible. Here's the XPath I want to use:

/data/stats/*_cost

This should match latest_cost, newest_cost, anything_cost, is there a way of doing this?

Cheers :-)
