> The same Path value, used in XPathValue and XmlTable->Path brings different results.
> That is for the following query:
> {code:sql}
> Select * From
>     (select '<root>
>         <item>
>             <id>id1</id>
>             <val>val1</val>
>         </item>
>     </root>' as resp) w,
>     XMLTABLE(
>         '/root' passing XMLPARSE(document w.resp) columns
>         valOption2 string PATH 'item[id = "id1"]/val'
>         --,valOption1 string PATH 'item[id/text() = "id1"]/val'
>     ) x;;
> {code} 
> returned value for "valOption2" will be changed from "val1" to "null" that is incorrect and unexpected behavior.
> Using "node/text()" in Path expressions may result in side effects.
