…and to complement this: With the upcoming version 9.3.2 of BaseX, local-name() function calls in predicates will be optimized by the query compiler.

Your query… *( declare function local:cloudWords( $Veld as xs:string ) as xs:string* { let $base := collection('IncidentRemarks/Incidentsv')/csv/record let $txt := string-join( $base/*[local-name() = $Veld]/text(), " ") return tokenize($txt,'(\s|[,.!:;]|[n][b][s][p][;])+') };

let $retValue := local:cloudWords("INC_RM") return $retValue

…will then be rewritten to…

tokenize( string-join( collection('IncidentRemarks/Incidentsv')/csv/record/INC_RM/text(), " " ), '(\s|[,.!:;]|[n][b][s][p][;])+' )

Cheers Christian

PS: Are you sure that your INC_RM text strings still contain "nbsp" substrings?

Hi,

I want to declare a function that can operate on various elements of a record. It should be possible to pass the element-name as parameter to the function.

I tried this:

declare function local:cloudWords( $Veld as xs:string ) as xs:string* { let $base := collection('IncidentRemarks/Incidentsv')/csv/record let $txt := string-join( $base/$Veld/text(), " ") let $words := tokenize($txt,'(\s|[,.!:;]|[n][b][s][p][;])+') return ($words) };

let $retValue := local:cloudWords("INC_RM") return $retValue

But I get this error: [XPTY0019] text(): node expected, xs:string found: "INC_RM".

Should I use xquery:eval to transform "$base/$Veld/text()" into "$base/INC_RM/text()"

For such simple cases with an element name it seems

$base/*[local-name() = $Veld]

suffices.
