Xpath / Xquery with colon

I am trying to get some information with xquery. But the xml-element has a colon with the name

I do know that the problem has to do something with the namespace but as I am working with a simple xquery intepreter i am not sure how to.

Here is my very approach but with 

let $e := doc('C:\Users\Katharina\workspace\BPMN\process_1.bpmn')
(: for $k in $e//*[name()='bpmn2:task']:)
for $k in $e
return $k

But I don't get anything with the changed code..

The XML -> 

<?xml version="1.0" encoding="UTF-8"?>

Just declare the namespace URI in your XQuery code.

declare namespace bpmn2="http://www.omg.org/spec/BPMN/20100524/MODEL";

let $e := doc('C:\Users\Katharina\workspace\BPMN\process_1.bpmn')

for $k in $e//bpmn2:task
    return $k
