$validNodes|%{$t=$_.Path;$_.User|write-host $t,$_}
The key to nesting foreach pipelines (i.e. pipelines with %{}) is to
store the $_ value (or the part of it you need) in a temp variable
before creating the nested one. It's also possible to access the
parent scope of $_ but I usually consider that just too messy to
bother with.
