An additional alternative is to use fetch:xml [1] or (if it’s only about retrieving random numbers) switching to the Random Module [2].

In the XQuery data model doc() do not change while a query is evaluated. So a doc() read once can in will be cached for that query. You may get what you want if you use %non-deterministic.

The built in random functions work like that.

Hello

I try to use random numbers from random.org.

Here my xpath

let $urand := function(){doc("https://www.random.org/integers/?num=1&min=0&max=1000000000&col=...) div 1000000000}

return for $i in 1 to 10 return $urand()

Which brings 10 time the same value, however, every run time a different one. What is wrong with this code?

Thanks in advance for your valuable input

Yours Leo
