I had the code

which was working fine.

You are checking for any of your qualifying preceding-siblings to be equal.


This was not giving the expected  result
not(translate(preceding-sibling::*[self::aaa][bbb]/bbb/ccc/@ddd,
$uppercaseAlphas, $lowercaseAlphas)=$zzz)

translate() acts on the first node in document order of a node set, so it is only checking one of your qualifying preceding-siblings.


but this is
not(preceding-sibling::*[self::aaa][translate(bbb/ccc/@ddd,
$uppercaseAlphas, $lowercaseAlphas)=$zzz])

The translate() in the predicate is acting on the one attribute descending from the aaa node, which is happening to work for you.


Is there any difference between the two???

Yes, a node set operand to a comparison operator acts on all members of the node set ... supplying a node set to translate() (and many other functions) acts on only the first member of that node set in document order ... in your case the most remote preceding-sibling.


I hope this helps.
