Hi,
if you query data from deep websites, you almost always end up with a
long get-link-download chain like:
doc("http://example.org";) // a [ condition 1 ] / doc( @href) //a [
condition 2 ] / doc(@href) //a [ condition 3 ] / doc(@href) / ....
Half the query is a / doc( @href) filler.
It is really ugly, isn't it?
How about replacing / doc( @href) with a single map operator? (or more
general / doc((@href,@src,@action)[1])
Like ~
Looks much better:
doc("http://example.org";) // a [ condition 1 ] ~ //a [ condition 2 ] ~
//a [ condition 3 ] ~ / ....
Or !!
doc("http://example.org";) // a [ condition 1 ] !! //a [ condition 2 ] !!
//a [ condition 3 ] !! / ....
Does it not?
What do you think?
I guess the WG is not going to add it soon? Are any other ~ or !!
operators planed?
Because it would be a shame to add it in an implementation, and then get
XQuery 4, where there is a ~ operator that does something completely
different.
Best,
Benito
