Answer by Alex Nikolaenkov for XPath wildcards on node name

With XPath 1.0 you can use /data/stats/*[substring-after(name(), '_cost') = ''] pattern. That checks if the element's name ends with the _cost suffix.

In XPath 2.0 there is fn:ends-with(str, str) and your corresponding expression will be *[ends-with(name(), '_cost')].
