Summary: XQ: substitution fails
Initial Comment:
The following query did not compile (on a "--nightly=current" build of last
week) using "pf -A"
element { "a" }{
for $a in doc("x.xml")//a
let $m := distinct-values($a//d)
for $q in distinct-values($a//c[d])
for $r in $m
where some $x in $a//c satisfies $x[e/d[contains(.,$r)] and a=$q]
return element { "a" } { $a//c }
}
the query returns: "fatal error: attribute `(NULL)' referenced in selection not
found"
however it does compile if the query is rewritten to: (in which $m is
substituted):
element { "a" }{
for $a in doc("x.xml")//a
for $q in distinct-values($a//c[d])
for $r in distinct-values($a//d)
where some $x in $a//c satisfies $x[e/d[contains(.,$r)] and a=$q]
return element { "a" } { $a//c }
}
