[basex-talk] Flexible update via function

Hello,

How to add/replace a complete node in a node tree, with done by a function and by according function parameters. That means with flexible instructions.

Such as:

declare function local:NodeAdd($XML, $XMLPath, $XMLValue) { ?? };

let $XML := <root><xml>text</xml></root> let $XMLAdd := <B>BBB</B> let $XMLPath := $XML/xml

return local:NodeAdd($XML, $XMLPath , $XMLAdd)

Problem: Following examples didn't work, because an internal reference to copy-XML-structure is needed/forced.

example 1: copy / modify

declare function local:NodeAdd($XML, $XMLPath, $XMLValue) {

copy $XML2 := $XML modify ( insert node $XMLValue into $XML2/xml ) return $XML2 };

But: Instead of into $XML2/xml,

into $XML/xml is needed, respectively into $XMLPath

Thanks a lot Michael
