Hi Darren.
I agree that it is very useful to take a path. The proposal you laid
out looks good. I suggest an addition, based on a useful feature of
ManifestServ: the ability to add values to the search, to narrow it
down.
Suppose you have two elements of type X, one with value 1 and one with
value 2, and you want to retrieve the value of //X/Y but only for the
second X element. Something like //X=1/Y could specify this. (Pretty
sure that Xpath has a way to specify this kind of thing, though I
don't know it off hand.)
I believe the xpath syntax equivalent is:
/element[index]
e.g.,
/X[1]/Y[0]
Darren:
I think the proposal is good - it's close enough to xpath to be
familiar, but different enough to be distinct. I do suggest putting the
"#num" and "?num" qualifiers in brackets, e.g.:
//obj[?3]/child[#3]/@someclass[0]/myobj.variable
