[xquery-talk] Masks in xquery

[Ghislain Fourny]

Hi Julio,

I am not aware of a built-in function for this, but could the following be what you are looking for? (It is very simplified, you might need to add error-handling)


declare function local:mask($number, $size)
{
  let $string := xs:string($number)
  let $length := string-length($string)
  return concat(
    string-join(for $i in 1 to $size - $length return "0", ""),
    $string)
};

local:mask(1000, 10)


Kind regards,
Ghislain
