My Xpath works with $x but not with document.evaluate – Javascript

I’m using AppleScript to control Safari. Now I need to execute a Javascript in Safari using AppleScript’s do javascript to evaluate an Xpath and use the return values in the AppleScript

This works

$x('//div/div/a').map(link => link.href)

But when I try something like this

document.evaluate(('//div/div/a').map(link => link.href), document, null, 0, null)

I get

TypeError: ('//div/div/a').map is not a function. (In '('//div/div/a').map(link => link.href)', '('//div/div/a').map' is undefined)

According to Google this error message means that I try to use map on non-array object. I think I understand what this means – (‘//div/div/a’) has not been evaluated before the .map(link => link.href) is executed but I can’t figure out how to express this statement so that map can be applied on an array.

If I add parenthesis like this

(document.evaluate(('//div/div/a')).map(link => link.href), document, null, 0, null)

document.evaluate don’t get enough arguments. I also tried

(document.evaluate(('//div/div/a'), document, null, 0, null))).map(link => link.href) thinking that document.evaluate would return an array but that got me the same error message as above map is not a function.

I’m not sure document.evaluate even gives a meaningful result:

document.evaluate(('//div/div/a'), document, null, XPathResult.ANY_TYPE, null)

XPathResult {resultType: 4, invalidIteratorState: false, iterateNext: function, snapshotItem: function, ANY_TYPE: 0, …} = $3

Isn’t this basically an empty result? That is, not an array?

How can I use ‘//div/div/a’).map(link => link.href in document.evaluate or similar function so I get an array-like datastructure as the result?

Update: I found this https://codereview.stackexchange.com/questions/167571/evaluating-an-xpath-with-document-evaluate-to-get-an-array-of-nodes and it works on a superficial level – but then I am back at my original problem – for some reason I can’t get the href-attribute using an xpath – to which the only solution seems to be to use .map(link => link.href)
