For now, Augeas implements the tiniest part of XPath notation, namely to
disambiguate multiple nodes with the same name,
e.g /files/etc/hosts/3/alias[2]
or /files/etc/ssh/sshd_config/AcceptEnv[last()]. 

The plan is to implement more of XPath to allow more flexible addressing
of nodes, so that you can say things like

         /files/etc/hosts/*[ipaddr = "127.0.0.1"]
         /files/etc/hosts/*[ipaddr = "127.0.0.1"]/alias[last() - 1]
         /augeas/files//error
         /files/etc/puppet/puppet.conf/section[value() = "main"]/vardir

Just not clear when I have time to do that :(
