Yes, As Asit mentioned both operators have significant difference . Here one more point about this operators . As per XQeury 1.0 strict and 0.9-ml version both will throw error if you not properly used both operators , But 1.0-ml , it’s doesn’t have any special difference , both will act as same unless otherwise you mention function mapping in the beginning of your XQuery code.

There was a difference between = and eq. eq is item operator, use for matching same item and = is sequence operator, use for matching in a sequence. MarkLogic 5.0 onwards both work similarly. But, for mail trail's code, it's behaviour is different as I tried in ML 8. ________________________________ Date: Mon, 29 Jun 2015 14:37:28 +0530 From: [email protected]<mailto:[email protected]> To: [email protected]<mailto:[email protected]> Subject: Re: [MarkLogic Dev General] Can anyone tell me why the result of the second xqery is empy? Geert, I was looking into the difference between eq and = in MarkLogic and found one article and it says "in the "1.0-ml" version of XQuery, there's no difference in behavior. eq behaves the same as =, etc." for more information please refer "https://developer.marklogic.com/blog/comparison-operators-whats-the-difference"; Are you referring the same of some other issue of =/eq?

Hi Geert, Below code is working fine, if we are assigning xml document in a variable, as you are doing. for $i in $xml/catalog/product/name where $i/../@dept<mailto:$i/../@dept> = 'WMN' return $i But, while using collection (retrieving document from MarkLogic collection) above code won't work.
