xpath Query for xpath extractor of Jmeter

问题

Can someone please provide me the xml query for retrieving the value of sessionId from the below response:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:createUserResponse xmlns:ns2="http://www.musicthp.com"     
                    isNewUser="false"
                    profileId="32109" 
                    sessionId="ryIlb+E5yj7FReA2w96uag=="
                    success="true">
<duration>316</duration>
</ns2:createUserResponse>

I tried using /ns2:createUserResponse/@sessionId and seems its not returning anything. I want to use this query in the XPATH extractor of jmeter. My requirement: I need to retrieve sessionId value using xpath extractor and use that value in the successive requests.

Thanks for your help in advance

Have you set JMeter to use namespaces?

JMeter has been reported to have problems with namespaces. If fiddling with settings won't help, here is a workaround for the root element

/*/@sessionId

Workaround for any element in a namespace is to use *[local-name() = 'element'] instead of prefix:element
