Examples
Example 24.636. Finding pairs of books
The following example is from the XQuery standard and it illustrates how to find pairs of books that have different titles but the same set of authors (possibly in a different order).
<bib>
{
for $book1 in document("bib.xml")/bib/book,
$book2 in document("bib.xml")/bib/book
where $book1/title > $book2/title
and $book1/author = $book2/author
return
<book-pair>
{ $book1/title, $book2/title }
</book-pair>
}
</bib>
