[MarkLogic Dev General] Regarding md5

Thanks for the suggestion. We will try using the xdmp:quote function
before calculating md5.
Another thing we noticed but forgot to mention earlier is given below
In file1.xml we stored the following content <root><a>a</a><b>b</b></root>
and in file2.xml we store <root><a>a</a><z><x>b</x></z></root>
when we executed the following code
let $a := fn:doc('/file1.xml')
let $b := fn:doc('/file2.xml')
let $x := xdmp:md5($a)
let $y := xdmp:md5($b)
This returned false. This is more or less similar to first part of the
earlier code but the current one returns a document node. Ideally in this
case also the md5 should return same for both the $x and $y right? can you
throw some light?
Thanks & Regards
