hi all,
I have an XML in the following form.
<evaluate oper="or">
<assert acrtreftype="prodattr" acrtidref="pa02" from="010" to="023"/>
<evaluate oper="and">
<assert acrtreftype="prodattr" acrtidref="pa02" from="001" to="005"/>
<assert acrtreftype="condition" acrtidref="c01" value="POST"/>
</evaluate>
<evaluate oper="and">
<assert acrtreftype="prodattr" acrtidref="pa02" value="006"/>
<assert acrtreftype="condition" acrtidref="c02" value="PRE"/>
</evaluate>
<assert>AIRPLANES WITH BENDIX BRAKES</assert>
</evaluate>

What I want to do is do this evaluation using xquery. Based on the oper attribute of evaluate , in xquery I need to do an and or or operations. Can some one suggest how to do this?
Thanks in advance

Hi Santhosh,
it's not too clear to me what should be done with the content of the various "assert" elements, but this could be a starting point

declare function local:process_assert($node as element()) as xs:boolean
{
(: replace it with some processing of the "assert" node :)
true()
};

declare function local:process_evaluate($node as element()) as xs:boolean
{
let $operands := for $child in $node/*
return
if(node-name($child) = xs:QName("assert")) then xs:int(local:process_assert($child))
else
if(node-name($child) = xs:QName("evaluate")) then xs:int(local:process_evaluate($child))
else (),
$sum := sum($operands)
return
if($node/@oper = "or") then $sum > 0
else
if($node/@oper = "and") then $sum = count($operands)
else false()
};

Hope this helps,
Alberto

Thanks a lot.
The assert statements will return boolean values, based on that evaluations will be done, the final output should be a boolean value. OR or AND operations will be applied to assert results.
I am new to XQuery and trying to learn for one of my project. And I am struggling to do the above descibed functionality.
