Hi *,

I am getting this error form this part of my code:

{
let $REG_80_510 := $doc/root/REG_80_510
where $REG_80_510 >> $REG_10 and (empty($REG_10/following-sibling::REG_10) or ($REG_80_510 << $REG_10/following-sibling::REG_10[1]))
return
$REG_80_510
}

Could you please help me to understand where problem is?

Regards

Hi Julio,
you are using "let" instead of "for"; "let" will assign the entire set of nodes to the variable, and ">>" cannot compare an entire set against a node.
