replace node in basex xml using xquery -

-

i trying replace node in xml using following code

string xquery_replace="xquery replace node cidem/shopfloor/foo[/cidem/shopfloor/shopfloorid=1] "+new_gbxml; session.execute(xquery_replace);

so want example change foo node of first shopfloor node

the xml has following content

<cidem>     <shopfloor>         <shopfloorid>1</shopfloorid>         <foo bar="2">             <baz>there</baz>         </foo>     </shopfloor>   <shopfloor>       <shopfloorid>2</shopfloorid>       <foo bar="5">           <baz>there</baz>       </foo>   </shopfloor> </cidem>

and receiving following error "[xuty0008] single element, text, attribute, comment or pi expected replace target."

any idea why?

the error message telling whats wrong.

"[xuty0008] single element, text, attribute, comment or pi expected replace target."

means expecting element or text or attribute... target replaced. path in query taking nowhere. read comment proper path.

for ex: if want replace value of attribute bar shopfloorid value 1, path should cidem/shopfloor[shopflorrid="1"]/foo/@bar
