Initial Comment:
The following xquery fails, using Monet4 Nov 2008 SP2.
$ cat error.xq
let $result := (let $items := doc("consumer04.xml")//properties/..
let $values :=
distinct-values((doc("consumer04.xml")//properties/..)/properties/content)
for $i in $items[properties/content]
where some $x in $values satisfies $x=$i/properties/content
return $i)
let $attrs := distinct-values(
for $j in $result/properties/*
return name($j)
)
let $props := doc("elements.xml")//proper...@name]
let $subprops := doc("elements.xml")//subproper...@name]
return element result {
element matches { count($result) },
element attributes {
let $usedprops := for $attr in $attrs return $pro...@name=$attr]
for $prop in $usedprops/.
return element { string($prop/@name) } {
attribute format { $prop/format },
attribute unit { $prop/unit },
attribute description { $prop/description },
for $subprop in $prop/subproperty
let $sub := $subpro...@name=$subprop]
return element { string(exactly-one($sub/@name)) } {
attribute format { $sub/format },
attribute unit { $sub/unit },
attribute description { $sub/description }
