xpath get value attributes concat string

I have a xml with several attributes like this:

<results value="1">
    <result value="111"></result>
    <result value="222"></result>
    <result value="333"></result>
    <result value="444"></result>
</results>

Are there any way to get all the values of the attributes and concat to every value a constant string? Output like that:

Value: 111
Value: 222
Value: 333
Value: 444

Thank you very much

Yes, that sounds feasible if you relies on XPath 2.0's functions library. You could write something like:

concat('Value: ',string-join((//result/@value), '\nValue: '))

or:

concat('Value: ',string-join((//result/@value), '&#10;Value: '))

depending on how you encode the newline character.

(tested using https://www.freeformatter.com/xpath-tester.html)

Another solution − if you only have a XPath 1.0 parser at hand − would consist in just evaluating //result/@value, then post-processing the node-list result so obtained in the programming language that you use.

EDIT: if you still need to get a nodelist as a result and only rely on XPath, you should prefer @JackFleeting's answer over my first suggestion.

(BTW I had also thought about the same solution as Jack's first, and tested it on http://www.xpathtester.com/xpath but this didn't work, probably because that online parser is buggy actually).

Using only pure xpath:

//results//result/concat("Value: ", @value)

Output:

Value: 111
Value: 222
Value: 333
Value: 444
