Question

my xml file :-

Answer 1

The following query should work:

let $ref-date := xs:date("1989-03-10")
let $data := <root>
    <name id="1">
        <region value="001">
            <date value="1989-03-09"/>
        </region>
    </name>
    <name id="2">
        <region value="002">
            <date value="1989-03-11"/>
        </region>
    </name>
</root>
return $data/name[region/date/xs:date(@value) lt $ref-date]
