Yes, that's possible, as of Augeas 0.6.0. As an example, this path
expression finds all entries in /etc/hosts whose IP address starts with
'192.':

        /files/etc/hosts/*[ipaddr =~ regexp("192\..*")]
        
You construct a regexp by passing a string with a regexp in extended
POSIX regex syntax to the regexp() function and match it against a node
with the '=~' operator.
