An attribute() is also a node(), so xdmp:node-replace() is the right
function...
Update is really easy...
let $oldYear as attribute() := doc("book.xml")/bib/book[1]/@year,
$newYear as attribute() := attribute year {2005}
return xdmp:node-replace($oldYear, $newYear)
Adding it initially (since the book element has no other attributes) is
slightly less straight forward...
let $book := doc("book.xml")/bib/book[1]
return
xdmp:node-replace($book,
element book {
attribute year {2009},
$book/*
}
)
If the book element had other attributes you could use
xdmp:node-insert-after() or xdmp:node-insert-before().

attributes for its element, suppose now if i want to add any
attributes to the element, then how do i do that without using
xdmp:node-replace() function

If i want to add an attribute "year" to book element . How to do it
without replacing the whole node.
let $b := doc("book.xml")//book
return
xdmp:node-replace($b[1], <book year="2009" >
<title>TCP/IP Illustrated</title>
<author><last>Stevens</last><first>W.</first></author>
<publisher>Addison-Wesley</publisher>
<price>65.95</price>
</book>)
2) If i want to change the attribute value (form 2009 to 2005) then

attribute value only using xquery.
Thanks and Regards,
