Thanks, seems the right idea, but browsing the code, decode just interprets a single xpath expression. While that is useful (and I've used xpath from the CL like before), I found I quickly needed to be able to chain them together etc.

pup (https://github.com/ericchiang/pup/blob/master/README.md) which apparently inspired xpup does seem to have this, e.g. chaining, but unfortunately it uses css selectors instead of xpath.
