xQuery IF condition does not work properly

Question

I am trying this condition, but it always exits through else way, could you help me? thanks

if ( $orderLine[osm:ProductSpecification/text()="X"] and osm:ExtensibleAttributes[osm:Name = "Y" or osm:Name = "Z"] and osm:NewValue/text() = "A" )
            then
                 <AccessType>X</AccessType>
            else
                 <AccessType>{$attribute/osm:NewValue/text()}</AccessType>
            )

Answer 1

I have solved the problem changing the filter scope:

if ( $orderLine[osm:ProductSpecification/text()="X" and osm:ExtensibleAttributes[osm:Name = "Y" or osm:Name = "Z"] and osm:NewValue/text() = "A" ]])
            then
                 <AccessType>X</AccessType>
            else
                 <AccessType>{$attribute/osm:NewValue/text()}</AccessType>
            )
